Abstract: A wiper assembly (120, 220) for a pulling over and toe lasting machine provides for variation of the configuration of the continuous wiping surface (146, 246) and of the leading edge (144, 244) of the wiper assembly. This is achieved by each wiper plate arrangement comprising two wiper plates (132, 152; 232, 252) pivotally connected to one another whereby their angular relationship can be varied. In one embodiment the wiper plate configuration is varied while the machine is in the rest position, and the wiper plates are then clamped in such position; in another embodiment the individual wiper plates (232, 252) are driven independently of one another whereby the configuration can be varied not only at the start of the lasting operation but during the course of the lasting operation; furthermore, by this independent means, the configuration can be varied differently for left and right shoes.

Abstract: The supports (9; 35) by which adhesive-applying nozzles (6) are supported in a shoe machine, e.g. a cement lasting machine, for tracking movement along opposite portions of a shoe bottom (5), are provided with mountings (34) by each of which either such a nozzle (6) or a sensing head (20) can be supported. In the latter case, as the sensing heads (20) are moved in the X-direction under the control of a stepping motor (18), the heads sense the edge of the insole (which may be provided with a black line (23, 24) and by feedback signals are caused to follow it, thereby determining the Y-axis movement corresponding to the X-axis movement necessary to guide the nozzle in the subsequent adhesive-applying operation. The Y-axis movement is stored at memory locations for which the X-direction movement values constitute the address.

Abstract: The pulling over assembly (2, 39) and lasting assembly (13, 40) of a pulling over and lasting machine are capable of being moved apart to enable a pulling over operation to be effected on one shoe at a first station (I) while a lasting operation is being completed on a further shoe at a second station (II). In one embodiment the pulling over assembly (2) moves bodily to the second station (II) at which the lasting assembly (13) is arranged; in a second embodiment the lasting assembly (40) moves to the first station (I) at which the pulling over assembly (39) is arranged. Each assembly (2, 13; 39, 40) has a heel rest (5, 19; 41, 50), the heel rests being so arranged as to carry out without collision the function of holding the shoe against lengthwise displacement.

Abstract: In a side (or side and seat) lasting machine two side lasting assemblies (230) are provided each comprising a side lasting roll (276) having a helical wiper element (282). As the rolls (276) are caused to operate progressively along opposite side portions of the shoe bottom from the heel breast line region toewardly, they are caused to rotate thus effecting an inwiping action on the lasting margin and pressing it against the insole margin. At a predetermined point in such progressive operation, at least one of the rolls (276) is displaced axially inwardly towards one another to enhance the inwiping action. This axial displacement may take place at the ball region of the shoe bottom, i.e. at or just before the end of the operation, and only the "outside" roll (276) or both rolls (276) may be so displaced.

Abstract: In a hydraulically operated pulling over and toe lasting machine both the operative position of the heel support (26), i.e. in which it holds the shoe by engagement with its heel end, and the position from which it initially moves to engage the shoe (the "next start" position) are controlled by electronic circuitry. Thus, an inductance switch (118) is actuated when the heel pad (100) engages the heel end of the shoe, said switch causing the supply of fluid to be shut off and locking the heel support in its operative position. For setting the "next start" position, on the other hand, selector switches (122,124) are provided each of which has an associated timer (T1,T2). At the end of a lasting cycle the heel support (26) is first fully retracted and then moves to its "next start" position under the control of the timer associated with the selected switch.

Abstract: In a pulling over and lasting machine in addition to a toe pincer there are provided two sets of side pincers, each set being mounted on a support pivotal about an axis extending heightwise of the shoe bottom and passing through or adjacent the toe pincer. Each pincer is adjustably mounted on its support but in addition each set is movable bodily, through its support, about its axis. The supports are movable equidistantly in opposite directions, i.e. towards and away from one another, into a selected one of a plurality of pre-set positions thus to accommodate to shoes of different widths. For moving the supports a plurality of cylinders are arranged in tandem and operable according to the selected pre-set position of the support.

Abstract: In a lasting machine shoes are supported with one end aligned with end lasting instrumentalities arranged to operate at that one end, and with the other end thus offset to the longitudinal center line of the instrumentalities (and thus of the machine). The support for the other end of the shoe includes a sensing arrangement mounted to slide transversely of the shoe. The sliding movement serves to distinguish left and right shoes and also to sense the amount of the offset. In addition the length of the shoe is measured from its initial lengthwise clamping. The various measurements are made electronically, e.g. using linear potentiometers. The signals are supplied to a control device (microprocessor) by which control signals are supplied to motors, e.g. stepping motors, for controlling tools, e.g. adhesive applying nozzles, to guide the latter along the sides of the shoe.

Abstract: In a pulling over and lasting machine in addition to a toe pincer there are provided two sets of side pincers, each set being mounted on a support pivotal about an axis extending heightwise of the shoe bottom and passing through or adjacent the toe pincer. Each pincer is adjustably mounted on its support but in addition each set is movable bodily, through its support, about its axis. In one embodiment the supports are movable only in opposite directions, i.e. towards and away from one another, thus to accommodate to shoes of different widths. In a second embodiment, on the other hand, in addition these supports are also movable in the same direction, thus to cause the pincers to be accommodated to left and right shoes.

Abstract: Method of and apparatus for side lasting shoes on lasts comprising a side tack insertion device, wherein the latter is moved along the lasting margin in an operating path following the course of the shank region. A friction closure element (tensioning strap, roller, smoothing runner) is moved stepwise in a longitudinal direction of the shoe and with each step is pressed periodically against the upper in a strip-like region associated with each tack insertion, whereby the upper is stretched in a direction towards the lasting margin.

Abstract: Apparatus for lasting footwear comprising a wiper assembly which lays the lasting margin about the insole which prior to lasting is pressed against the last by an adhesive injector plate. By a control the movement of the wiper assembly is arrested in an intermediate position in which the wiper assembly has just traversed the insole margin. By means of a signalling device a "fall away" signal which causes the injector plate to fall away from the insole is supplied when the wiper assembly is arrested. Adjacent the injector plate are provided adhesive injector nozzles which are movable away from the plate. By means of a latching member or a timer member it is ensured that the wiper assembly closes only if the adhesive injector nozzles cannot hinder the movement of the wiper assembly.

Abstract: A machine for lasting the heel of a shoe comprising a shoe last support including an axially displaceable column having a free end. The support is displaceable from a first retracted position to an advanced position and a shoe last is mounted on the free end of the column for limited rocking movement relative thereto to permit realignment of the shoe last. The column may be elevated from a lower position, and when so elevated, strikes the inner edge portion of the heel band wiper plate which has been displaced to a selected position in interference with an edge portion of the shoe last. Such upward movement of the shoe last will be, accordingly, stopped by the interfering edge portion of the heel band wiper plate and the shoe last will be automatically aligned into uniform engagement therewith. The column is locked at the stopped position and a heel band forcefully engages the stopped and aligned shoe last to maintain the shoe last at that position in that alignment.

Abstract: Adhesive applicator device in a cement lasting machine comprising an adhesive applicator element provided for the shoe toe and two adhesive rails adjacent the adhesive applicator element. The adhesive applicator rails are secured to the adhesive applicator element by means of a ball joint and on the opposite side are connected by a further ball joint with a push-rod. By virtue of the two-sided ball joint journalling the two adhesive applicator rails can thus accommodate to any position of the lasting margin.

Abstract: Device for tensioning a shoe upper on a last and for laying its lasting margin over in the ball and shank region, wherein the shoe upper is first pressed against the last by means of a presser member, whereafter a band secured to the presser member is tensioned about the shoe upper in a direction towards the last bottom. The bands which embrace the last from both sides are brought together in tension in the middle of the insole.

Abstract: A heel nailing machine having a holddown for the heel which clamps the heel against movement during attachment. The holddown is then moved upwards to lift the heel and attached shoe off the stand. The holddown then swings to one side and the shoe is released. The shoe is thus automatically ejected from the machine.

Abstract: In a tack seat lasting machine the wipers are moved lenthwise of the shoe and inwardly thereof under the action of a single piston-and-cylinder arrangement. For setting the appropriate "nail pattern", the action of said piston-and-cylinder arrangement is terminated by adjustable stroke limiting means, comprising a valve actuated by an abutment, the valve moving with the wipers and the abutment being adjustably positioned in the path of the valve. A further abutment, spaced from the first-mentioned abutment, controls the rest position of the wipers. The wipers are arranged symmetrically centrally of the machine, and the heel band is capable of clamping a shoe in the position in which it is presented by the operator, thereby avoiding the need to adjust the wiper for lefts and rights.

Abstract: In a pulling over and toe lasting machine, the pincers first grip the lasting margin above the wiping plane, whereafter the upper is tensioned about its last by upward movement of the last support, from an initial, lowered, position to a position in which the last bottom is in the wiping plane, and by downward movement of the pincers. The machine also comprises auxiliary means by which any wiper remaining in the wiping plane after the upper has been tensioned as aforesaid can be moved downwardly out of said plane so as not to impede the in-wiping movement of the wipers. When the auxiliary means is actuated, furthermore, the gripping force applied by the pincers to the upper is reduced to allow slippage of the upper in the pincers.

Abstract: An outer molding band for a shoe upper backpart portion molding machine comprises two support portions, each carrying a block of relatively hard rubber, each block in turn carrying a molding cushion which is shaped to the shape of an inner mold. A cover, which acts as a diaphragm, to which air may be admitted, is arranged between the diaphragm and the support portion, to press the block, and thus the mold cushion carried therewith, against the inner form. The two support portions are pivotable inwardly to a position in which the mold cushions supported thereby engage the inner mold, or a shoe upper placed over the inner mold, and where air may be admitted as aforementioned, to apply a molding pressure to that shoe upper.

Abstract: A shoe machine for pulling and lasting shoe uppers and insoles on lasts has a pair of wiping elements, one operating heelwardly of the other in the joint region. After the upper has been pulled over and the insole has been cemented, the first wiping elements wipe in the upper margin at the joint with a toeward motion, which wiping elements then retract. The second wiping elements wipe in adjacent portions of the lasting margin, the wiping action of the second wipers overlapping that of the first wiping elements to wipe down any creases formed thereby. The main toe wiper plates operate to wipe in the toe and forepart portions of the upper. The insole cementing plate has heelward extensions hinged thereto which are yieldably urged upward by springs. Cement is fed to the extensions via passageways in their connective pivot pins.
