Abstract: A device for transporting film (5), in particular unperforated film (5) without slippage, in particular intermittently, powered by at least one electric motor (8), having at least one element such as a needle point (2) mechanically engage film (5) by entering it and transporting film (5) from a start position to a stop position. An element such as a pressure plate (7) may be used in one embodiment to hold the film steady during exposure and a movable element (7) may act on the film to hold it during exposure. At least one mark may be exposed on film (5) to aid in picture registration. At least one roller (31) controls the length of loops of film (5) before and after the aperture. The roller (31) may transport the film (5) by friction, or, in another embodiment the roller (31) may have radially mounted needles (2) which penetrate film (5) to hold film (5) while transporting it.

Abstract: A device for picking up a strip of film, in particular for removing a support film from a robot for automatically placing electronic components, wherein the film is grasped either between two wheels rotating in opposite directions, the wheel entraining the wheel in one direction and then running over the film in the opposite direction, or else between the fixed jaw and the moving jaw of a clamp hinged about a pin, the moving jaw being moved towards the fixed jaw by coming into contact with a part of the machine which then moves the clamp as a whole together with the film.

Abstract: A feed device for advancing a web into a processing station which acts on the web while the web is in a standstill position. The feeding device includes a first drive roller around which a second swivel roller oscillates between an upstream and downstream position to create a loop to take up the web during a dwell in the movement of the web through the processing station. The swivel roller is driven at the same speed as the drive roller by an arrangement of drive pinion and a counterweight is also rotated at the same rate by a gear arrangement. The counterweight is mounted on a lever which will oscillate in an opposite direction to the movement of the swivel roller so that the moment of inertias are balanced during operation of the device and the torque on the drive for the rollers is balanced.

Abstract: A roll type stock feed apparatus for a power press. The stock feed apparatus has a pneumatic system for actuating the feed rolls between stock feed and stock release positions. Pressurized air in a substantially constant pressure is applied to one side of a pneumatic actuator to press the feed rolls into feeding engagement with strip stock between the rolls, and pressurized air is selectively applied and exhausted from the other side of the actuator piston to respectively release and apply feeding pressure to the stock feed rolls. An adjustable stop is provided to limit movement of the actuator pistons in a stock release direction.

Abstract: Pivot arms which carry the pressing bar are hingedly mounted to the rocker. At their opposite ends these pivot arms are hingedly mounted such to the frame that in one position the axis of rotation of the lower feeding roller coincides with the pivotal axis of the pivotal point at which the pivot arms are hingedly mounted to the frame. The pressing bar is thereby hingedly mounted via a link connection to a pivot point at the frame that a parallelogram of movements is provided, based on which the pressing bar is moved exactly perpendicularly against the workpiece to be arrestingly pressed.

Abstract: The present invention relates to a hog ring clamping device such as a C ring clamping device. In the hog ring clamping device of the invention, a knock pin is mounted to a movable member of a jaw driving unit, a pivotable member is mounted to a hog ring clamping device body, the pivotable member is pushed against the knock pin by means of spring, a feed member is mounted to the pivotable member so that it can come into contact with hog rings engaged with a magazine, and a presser wheel is mounted to the hog ring clamping device body through a unidirectional rotating unit so as to be in contact with the hog rings engaged with the magazine.

Abstract: An apparatus for preventing tape from being rolled on a capstan or pinch roller including a pinch roller having a ratchet wheel rotated integrally with the pinch roller, a tape contacting plate having a pawl capable of engaging the ratchet wheel, and a resilient plate for providing a biasing force in response to tape tension is provided. The pinch roller is usable to rotate when the tape becomes lose and is able to rotate when the tape becomes taut.

Abstract: A roll feed apparatus for feeding a sheet material successively to different working stations. The apparatus includes an oscillation driving device, a main sector roll integrally carried by a main roll shaft and adapted to be oscillatorily driven by the oscillation driving device, and a sub-sector roll integrally carried by a sub-roll shaft extending in parallel with the main roll shaft. The sub-sector roll is adapted to cooperate with the main sector roll in clamping a sheet material therebetween and feeding the same.

Abstract: Device for infeeding a strip of flexible material for use in a machine for binding articles in particular for edging parts for boots and shoes. The infeed device has a quadrant mounted in advance of a cutting mechanism on the machine.

Abstract: A contacting device for making a wire connection on a microcircuit by applying ultrasonics or thermocompression. A contacting horn is provided with a capillary which, in turn, is associated with a wire clamping device for feeding or clamping the wire during movement of the contacting horn. The wire clamping device has two clamping members for grasping the wire. The clamping members are movable relative to each other for clamping the wire, and both are arranged to pivot jointly to move the clamped wire in its lengthwise direction. A controllable actuation unit is each associated with the second clamping member which moves relative to the first, and the two clamping members jointly. The clamping members may be formed as a strip for grasping the wire between outer end regions. The second clamping member is mounted on a support of the first clamping member, and its outer end is pressed by a leaf spring fastened to the first clamping member.

Abstract: A bonding head of the type having a bonding tool mounted in the bonding tool holder is provided with a pivotable wire clamp which is movable toward and away from the rear of the bonding tool. The wire clamp is pivotally movable to three distinct positions by a single solenoid. The wire clamp is opened and closed by a second solenoid. The solenoids are mounted on the pivot axis of the bonding tool holder in a manner which substantially prevents the shock force of actuation of the solenoid from being imparted into the bonding tool holder or the bonding tool during a bonding operation.

Abstract: A device for stepwise feeding a hose for packaging products, in particular fruit and vegetable products comprises a frame, pincer gripping jaws swivel supported by the frame, a first jack for moving the gripping jaws between a raised position and a lowered position and a second jack for operating the gripping jaws to grip the lower closed end of a packaging sleeve when the gripping jaws are in the raised position and drag that end downwards and then release it when the gripping jaws are moved to the lowered position.

Abstract: The feeding mechanism serves to intermittently feed stock to a processing machine and comprises a rocker lever having at its outer end an arcuate surface shaped according to an arc of a circle, crank drive comprising a crank which is operatively connected to said rocker lever, said crank drive being operable to impart an oscillation to said rocker lever, a clamping roller adapted to cooperate with said arcuate surface and forming a feeding clamp therewith, a retaining clamp for holding said stock in position, and control means for cyclically opening and closing said feeding clamp and retaining clamp in alternation.

Abstract: The format of sheet material being printed is controlled and may be varied during successive printing cycles of a continuously operating printing machine by means of an assembly, preferably including a step-by-step motor for driving the sheet, which assembly is controlled by pulses and moves the sheet during a period within which no printing takes place.
