Abstract: The machine of the present invention manufactures low-cost garments out of two plys of web material, preferably nonwoven material. It includes a pair of feeder mechanisms to supply two separate sheets of the web material through cutter mechanisms where the webs are cut into shapes suitable for the desired garment. The shapes of one sheet are larger than the shapes of the other sheet. The sheet with the larger shape is placed on a carrier, and the sheet with the smaller shape is placed thereupon. As the combined sheets are moved by the carrier, a plurality of folding mechanisms turns the edges of the larger sheet around the edges of the smaller sheet to create a seam which is subsequently secured, as by adhesives or sewing. The carrier may be either a rotating cylinder or it may move longitudinally. The seams may be created along machine direction lines, cross machine direction lines, or along lines at acute angles to either the direction of movement or perpendicular thereto.

Abstract: A clamp is shown for holding a log of paper while a log-saw or cutting machine cuts shorter lengths of toilet-paper rolls or rolls of kitchen towels or similar all-purpose wipers from the log. The clamp is arranged adjacent a seat or support for the log as well as adjacent a cutting blade. The clamp includes, for each log seat, and on opposite sides of a cutting plane (T--T) through which the blade passes, a pair of adjustable and symmetrically arcuate strips (212, 214) secured to supports (207, 209). The strips are of flexible material with end portions which tend to spring outwardly. A strap (222) is anchored to a retention holder (224) and an adjustment holder (246). The strap surrounds the pair of strips (212, 214) and can change the arrangement thereof. A drive (240, 262) simultaneously adjusts both the effective length of the strap (222) and the symmetrical angular orientations of two rods (228A, 228B) and, consequently, of two cradles (218) on which the strips are supported.

The transportation unit comprises a plurality of conveyors in series which can be operated at varying speeds so as to allow separation of a first series of sheets from a successive second series of sheets; with one of said conveyors there is associated a retaining means for holding the rear portion of the first sheet of said second series, which retaining means comprises a gripper member able to perform an alternating movement along the conveyor with which said gripper member is associated.

Abstract: In a machine for packaging individual items such as 6-packs of beverages into a container, the containers are moved along a lower conveyor and the items are moved along an upper conveyor. A pusher bar pushes the items off the upper conveyor whereupon they drop by gravity into the containers. Shortly before the items begin to fall, the pusher bar rotates frictionally against the back of the item whereby that the falling speed of the back of the item as it leaves the upper conveyor is increased so that both the backside and the frontside of the item drop into the container with the sides vertically aligned.

Abstract: A surface automatic rewinder for winding web material (N) in logs or rolls (R) is described, including a first winder roller (1), a second winder roller (3) which defines, with the first winder roller, a nip (5) through which the web material is fed, core feeder (19, 21) to feed the cores (A) on which the web material is wound for the formation of rolls or logs, and an inserter (27) for inserting the cores into the nip (5). The rewinder is characterized in that the inserter (27) may be moved to an inoperative position whereupon the winding of the web material can be accomplished without a winding core.

Abstract: The large overhead bi-fold doors of the present invention are hinged along a centerline and hung by hinges from the top of the door opening. A motor mounted inside and above the door opening is connected to one end of a cable, the other end of which passes around a pulley at the bottom of the door and then upwardly to a latching mechanism located beneath the horizontal hinge line of the doors. When the motor is activated, the cable pulls on a dog or arm connected to a shaft which also carries the hook of a latching device. The hook engages a strike attached to the frame of the building on which the door is mounted, and when the motor is activated, the cable pulls on the dog which disengages the hook from the strike and further tension on the cable by the motor raises the door to an elevated position.

Abstract: A surface rewinding machine for the formation of logs of web material has a winding roller (1) onto which the web material (N) is fed. The winding roller has a surface portion (1A), extending substantially parallel to the roller axis and having a coefficient of friction lower than that of the adjoining surface. The web is pressed at preset moments by a pusher (3) against that portion of the surface of the winding roller having low coefficient of friction so as to tear the web material.

Abstract: A rewinding machine for the production of logs (R) of web material (N) without a core comprises: a first winding roller (1) onto which the web material is fed; a second winding roller (3) rotating in the same direction as the first roller and forming a nip (4) therewith through which the web material passes; an actuator and element (15, 17) to move the surface of the second winding roller (3) toward the first winding roller (1); and a separator to sever the web material at the end of the winding thereof to form a log (R). Provision is also made for a surface (21, 21A) supporting the log (R2) in the process of formation and located upstream of the nip (4) between the rollers (1, 3).

Abstract: The machine cuts a roll or log (L) of web material into a plurality of small rolls (R). It includes a unit (17) rotating about an axis (A--A) parallel to the axis of the log (L) to be cut. The unit carries a cutting blade (19) rotating about an axis (B--B) parallel to the axis (A--A) of the unit (17). A driving device (61, 63) moves the cutting tool (19) into a reciprocating forward and backward motion parallel to the axis of the log (L) to be cut. At least at the time when the blade cuts the log, the blade moves parallel to the moving log at a translation speed substantially equal to the feeding speed of the log (L), so as to allow the cutting of small rolls (R) without stopping the log (L).

Abstract: The fastening device for interconnecting two flat sheets of metal includes a generally rectangular hole in one of the sheets and a generally H-shaped hole in the other. The H-shaped hole includes a pair of inwardly-facing, tapered portions which are adapted to be bent into the rectangular hole of the other member. The dimensions of the tabs are such that when bent inwardly into the rectangular hole, the edges of the tabs are forced against the edges of the rectangular hole so as to cause the two members to be rigidly and securely interconnected without the necessity of the tabs being bent backwardly behind the rectangular opening in the other member.

Abstract: A hitch or towing device to connect a trailer having at least two swivelable ground-contacting wheels to an automobile or similar prime mover includes two arms to connect the trailer to the prime mover. The arms are flexible in a vertical direction but rigid in a longitudinal and in a sidewise direction. This permits the automobile to push the trailer backwards and also permits relative motion between the trailer and the automobile in roll and pitch but not in yaw. In a preferred embodiment the arms connecting the trailer to the automobile are leaf springs, and couplings permanently fastened to the automobile engage the front end of the springs in a hinge-like manner, the hinge-pin being easily removable to facilitate connecting and disconnecting of trailer and automobile.

Abstract: The apparatus for holding a log or long roll (L) of web material during the cutting thereof along a plane perpendicular to the log axis, includes: a plurality of clamping elements distributed in a circle around the log (L). The clamping elements can be moved so as to clamp the log during the cut and also to be released so as to allow the log to axially move between cuts. At least one actuator causes the movement of the clamping elements, and connectors which connect the clamping elements to one another to provide a simultaneous movement thereof by said actuator. Each clamping element pivots around an axis so as to cause clamping of the log. The connectors control the pivoting of said clamping elements.
