Abstract: A feed mechanism includes a feed slide movable between a retracted position and an advanced position. The feed slide is configured to feed a product strip during a feed stroke as the feed slide is moved from the retracted position to the advanced position and the feed slide is movable with respect to the product strip during a return stroke as the feed slide is moved from the advanced position to the retracted position. The feed mechanism also includes feed fingers pivotally coupled to the feed slide at corresponding attachment points. The feed fingers are movable between an engaged position and a released position, wherein the feed fingers are configured to contact the product strip in the engaged position and the feed fingers are configured to be positioned away from the product strip in the released position. The feed fingers are moved to the released position prior to the feed slide moving along the return stroke.

Abstract: A machine (70) for receiving a continuous strip (10) of elongated products (12) mutually attached end to end includes a frame (82) and is arranged for incrementally feeding the strip of products and performing a manufacturing operation therewith. Each two adjacent products (12) are attached at an indentation (14). The machine include a feed mechanism (90) for incrementally feeding the strip of products. The feed mechanism includes first and second feed fingers (216, 218) mutually opposed on opposite sides of a feed track (108). The first and second feed fingers are movable toward the strip of product until in feeding engagement therewith without gripping the strip of products. The feed mechanism includes a drive carriage (94) and a follower carriage (96) arranged for independent sliding movement along the direction of feed and return. The feed track extends through both the drive carriage and follower carriage to guide the strip of product.

Abstract: A tape feeder has a driving member which performs reciprocating motion, and a tape-advancing mechanism driven by the driving member for intermittently advancing a tape containing electronic parts to thereby position each of the electronic parts at a predetermined takeout position. The tape-advancing mechanism comprises a driving force-converting device for converting a driving force received from the driving member to a driving force for use in tape-advancing motion of the tape-advancing mechanism, such that speed of the tape-advancing motion is varied as the tape-advancing mechanism is driven by the driving member.

Abstract: In a continuous tensionless treatment device for cloth, comprising a treatment liquid bath, a feed device for feeding a cloth being wavily curved, an upper cradle, a lower cradle and drive means of these cradles, each of horizontal beams arranged in the upper cradle for performing cloth crumpling action and washing action is composed of a first horizontal beam having V-like slant surfaces, a second horizontal beam hanging a member having many small through holes, and a partition plate arranged between both beams. These three members are arranged in prescribed relation so that in a space (stirring chamber) between the first horizontal beam and the second horizontal beam the treatment liquid is subjected to the rapid stirring flow.

Abstract: In a drive device operated by pressure fluid a progressive linear or swinging or rotary movement of a driven element is produced by means of at least one lifting element. Between the lifting element and the driven element there is arranged at least one wedge which carries out a stepwise reciprocating movement under the influence of the lifting element. In this way the driven element is pushed forward step by step in the loaded direction via a force locking. This drive device permits a force-locked connection to the object to be moved.

Abstract: A tape supply cartridge for supplying tape and ribbon to a lettering apparatus having a mechanism for creating a lettering force and a mechanism for positioning a character to be lettered into lettering position. The cartridge includes an improved device for advancing and assuring alignment of the tape. The cartridge also includes a mechanism for preventing the ribbon supply spool from free wheeling and improved structure for interfacing with the lettering machine to advance the tape.

Abstract: The disclosed method consists in that the electrode wire has the portion thereof intermediate the supply coil and the welding arc alternatingly retained at one of two points, with an effort applied to the wire in the respective retaining point, causing transverse oscillation of the wire. The effort is applied at an angle substantially short of 90.degree. relative to the direction of feeding the wire toward the welding zone. The apparatus of performing the disclosed method comprises a plurality of gripping means for retaining the wire, each including a plate apertured for passage of the wire and a spring accommodated between a housing and the plate, the plate of one of the gripping means being mounted for reciprocation in the direction of feeding the wire toward the welding zone and having its side surface adapted to cooperate with an actuator mounted on the output shaft of the drive effecting the feed and transverse oscillations of the wire advanced toward the welding zone.

Abstract: A mechanism for moving a tape through a printing apparatus in which said mechanism includes a back-space shuttle mounted to a frame for reciprocal movement and an advancing shuttle mounted to the back-space shuttle for reciprocal movement. Movement of the advancing shuttle in its operative direction by an advancing actuation arm of the printing apparatus causes the tape to be gripped by the advancing shuttle and advanced. The tape slips through the back-space shuttle during movement of the advancing shuttle in its operative direction. Movement of the back-space shuttle in its operative direction by a back space actuation slide of the printing apparatus causes the tape to be gripped by the back-space shuttle and back-spaced. The tape slips through the advancing shuttle during movement of the back-space shuttle in its operative direction.

Abstract: Disclosed is apparatus for feeding length stock into a work tool such as a punch press. The feed apparatus includes a pneumatically operated traveling clamp and a pneumatically operated fixed position clamp. The traveling clamp is linearly reciprocated between two positions by a pneumatically operated lever and linkage which varies the velocity of the traveling clamp proportionately with distance from the fixed position clamp to decelerate the traveling clamp as the feed stock reaches the desired position in the work tool. Interdependent pneumatic control systems for sequencing the advancement of the stock with the cyclic operation of the work tool and for sequencing the clamps with the feed advancing mechanism are also disclosed.

Abstract: Method of controlling with heightened accuracy a processing machine driven t different operating speeds and having a machine part moving through a predetermined full range, the processing machine, at an initial setting of the moving machine part, within a given tolerance range, repeatedly permitting start-up of a processing cycle that has been instituted in advance through a precontrolled time period dependent upon the operating speed and which includes a control commencement build-up time period and a full range displacement time period, which includes interposing a blocking time period between the control commencement build-up time period and the full range displacement time period, the blocking time period always ending at the same position in the displacement range of the moving machine part, blocking the full range displacement by the moving machine part until the end of the blocking time period, and advancing the start of the control commencement build-up time period in accordance with the blocking time
