Abstract: The invention relates to a method and a device for the positionally correct winding up of a metal strip in a coiling device, the hot strip being fed to the coiling device by a driving device with driving rollers, the driving rollers being tiltable in relation to one another by a controller by means of actuators for changing the gap between the driving rollers, and the controller being fed the position of the edge of the hot strip upstream of the driving device as a measured variable and as a setpoint reference variable, an optimization of the winding result of the rolled strip coil being achieved by the surface geometry of the rolled strip being determined as a measured variable and fed to the controller.

Abstract: A device in a wire rolling mill includes a pair of grooved rolls. Each grooved roll is fixedly attached to the free end of a rotatably supported spindle. Each grooved roll is positionable relative to the other so that they between themselves define a rolling gap of adjustable size. At least one of the spindles is arranged integrally with the output shaft of an electro motor. The electro motor drives the spindle directly thereby avoiding heavy and space-requiring transmissions.

Abstract: A web and an associated web feeding and handling apparatus for performing a work operation on the web is disclosed. The apparatus feeds the web in a feed direction longitudinally of itself by means of a friction drive. The operation of the drive is controlled by lateral and longitudinal alignment indicia located on the web which insure that the web is properly aligned with the feed direction as the web is initially fed into and then through the apparatus, and to insure that any bowing of the web during the work operation is corrected or compensated for.

Abstract: A label separator apparatus has a label separating member for separating labels one by one from a long and narrow label carrying paper, on which the labels are adhered, by acutely turning the carrying paper toward a no-label-adhered side thereof while the carrying paper is moved in its longitudinal direction. The label separator apparatus further has a label-rising restrictor located above the label being separated form the paper which contacts a rear end portion of the label which is being separated while the label rises together with the paper from the separating member, so that the label is prevented from being completely separated from the paper.

Abstract: A recording apparatus and, more particularly, a so-called thermal printer employs a thermal head as a recording head. A platen roller is in pressing engagement with the recording head and recording elements pass between the two. Biasing forces exerted on opposite ends of the recording head cause it to deform slightly. To accommodate for this deformation, the diameter of the platen roller is greater in the middle than at its opposite ends. This construction assures that both the recording head and the platen roller are pressed against each other under a uniform force, so that ink density irregularity on the recording paper, creasing of the recording paper and the ink sheet, and recording density irregularity resulting therefrom can be prevented, and thus stable recording performance can be assured.

Abstract: A pair of transport rollers for transporting therebetween a tape or sheet material, such as film, for example in a wet processing device, in which one roller is cylindrical and another roller includes two outwardly converging conical end portions and a cylindrical intermediate portion, whereby two or more films can be transported by the roller pair simultaneously.

Abstract: A machine for winding, with a very short pitch, on a cable (1), at least one metal sheathing wire (5), comprising a first means for translatably moving a rectilinear portion of the cable in accordance with its axis and at least one coil (4) for distribution of said wire arranged on a coil-holder (3) subjected to turning around said cable in a perpendicular plane to said axis, with said wire passing on a grooved pulley (8) which is arranged between the coil and the cable and which has a fixed axis in relation to the coil, characterized in that the pulley (8) is provided with a driving means (9, 18, 20, 21, 22, 23) in rotation at an adjustable speed.

Abstract: A device for transporting a flexible strip (11) along a guide (15) by means of conical pressure rollers (35 and 45), whose apices face each other. The pressure rollers (35 and 45) are loaded by a spring (65, 135) common to both rollers, as a result of which an accurately defined directional force is obtained towards the guide (15).

Abstract: The specification describes a mechanism for controllably advancing material such as wire to a work station. The mechanism includes two frusto-conical shaped wheels mounted in a face to face relationship so that the wire is pulled through the nip formed by a rotation of the wheels. One wheel has an associated bias adjustment means which is adapted to vary the pressure exerted by one wheel on the other. A flexible wire guide, and an adjustable spool holder form part of the mechanism.

Abstract: The self-centering feeding device (20') for elongated objects such as logs includes a conveyor means (30) carried by a parallel mechanism having a vertical stationary part. The parallel mechanism is connected to a mechanical engagement means (26) and is controlled by a driving means (28) activated when an object on the conveyor means reaches a predetermined position, and is then kept activated the whole time during which the object is fed-through. The object is thus firmly clamped between the conveyor means and the engagement means and has no possibility to rotate about its longitudinal axis. The conveyor means may therefore be much shorter than the object. The invention is suitable for general application, but in particular for application in the log processing industry.

Abstract: There is described and shown apparatus which is for the controlled feeding and taking-off of a thread 12 into or out of a thread treatment section 2 (for example a heating zone of a heat setting arrangement), and which comprises an externally-driven tapered drive roll 4 upon which bear two tapered counter-pressure rolls 5, 6, whereby the thread 12 can be fed into, and taken-off from, the treatment section 2, using only a single drive means for this feeding and taking-off. The arrangement shown is provided with two thread guide members 9, 10 of fork form, which are swivellable to vary thread tension, one of said guides being swivellable to move the thread engaged between roll 4 and roll 5 along one side of roll 4, and the other of said guides being swivellable to move thread engaged between roll 4 and roll 6 along the other side of roll 4.

Abstract: A device for laminating a piece of adhesive coated laminating tape onto a section of lettered tape comprising a housing having a first roller rotatably mounted between the side walls of the housing, a second roller rotatably mounted between the side walls of the housing, a supply of adhesive coated tape rotatably mounted within the housing and rearwardly of the first and second rollers, a guide for guiding a section of the lettered tape toward the laminating station and a cut-off edge for severing the adhesive coated tape.

Abstract: A photoprocessor for photosensitive webs includes a plurality of tanks containing photoprocessing solution and a dryer. The web is transported through the tank by a plurality of opposed spaced pairs of oppositely oriented driven tapered rollers. The transport speed of the web through the tank is determined by a pair of opposed cylindrical rollers at the exit of the last tank. The cylindrical rollers are driven at a tangential velocity which is approximately equal to the tangential velocity at the centers of the tapered rollers. A loader at the inlet end of the processor includes driven and idler rollers which are normally out of engagement and which are brought into engagement to drive the web into the processor for a selected time period when the web is first sensed at the inlet end of the processor.

Abstract: Tubular wire comprising a calcium-containing solidified core in a thin steel sheath is fed between successive sets of resiliently-engaging pinch and feed rollers having aligned V-shaped indented peripheries. A wide range of wire diameters from about 3 to 8 mm are accommodated between a feed roller having an indented relatively sharp obtuse angle of about 120.degree. and a pinch roller having an indented relatively shallow obtuse angle of about 150.degree.. The peripheral walls of the feed rollers have staggered serrations for gripping the wire and a grooved channel between them for removing debris. The pinch rollers of a pair of successive sets are positioned slightly outboard of the feed rollers to keep the wire straight. Simultaneous feeding of two or more wires is provided through a plurality of sets having a common axis of rotation for the feed rollers.

Abstract: A projector for motion picture film includes a servo motor which is controlled to advance film frame by frame to a projection station. A capstan on each side of the projection station is controlled to maintain film loops of substantially constant size and an associated reel motor delivers film to and takes film from each capstan. Each associated capstan and reel motor are controlled so as to maintain substantially constant tension on the film. A film guide defines the projection station and also includes provision for masking peripheral areas of each frame. Each capstan and an associated pinch roller are designed so as to eliminate creeping of film from between the two. A circuit for controlling the reel motors is arranged to permit fast winding of film directly from one reel to the other with an automatic braking feature.
