Abstract: A adjusting nut is arranged on a threaded spindle. The adjusting nut supports a first double arm lever unit with a first and a second arm. A second double arm lever unit is pivotally mounted at its first arm through a connecting strip to the second arm of the first double arm unit. The second arm of the second double arm unit is pivotally mounted through a control rod unit to a rocker.

The information is registered such that it is placed at a predetermined location on different tape segments.

Abstract: A manually actuatable, part feeder presents at least one exposed part, with an appropriate orientation for picking and placing, to an operator in a pick station, in response to the operator providing a feed command. A cover take-up mechanism can be used to remove a cover tape from the carrier such that the operator receives the exposed part or parts to be picked. Tape advance is achieved by applying forces to the carrier tape to advance the pocketed component carrying portion. Variable widths of carriers can be accommodated in the feeder. A pair of movable hold-down rails, laterally adjustable with respect to one another, makes it possible to feed carriers having a wide range of widths simply by adjusting the spacing of the rails relative to one another.

Abstract: The crank assembly of the advancing apparatus is eccentrically supported in an intermediate shaft. This intermediate shaft is in turn supported in an oscillating slide. Accordingly, the oscillating movement of the slide is superimposed over such of the driving pivot of the crank assembly. The intermediate shaft includes a cam disk. Due to the cam disk the intermediate shaft oscillates in operation and causes in turn the oscillating movement of the slide, which oscillating movement proceeds oppositely to the oscillating movement of the driving pivot. The sum of these two movements in the zones of the end positions thereof is accordingly zero. Accordingly, the driving pivot is at rest over a prolonged time span. Due to this prolonged rest period between individual feeding steps, elastical deformations of working structures and of the workpiece being worked upon, can attenuate and fade out prior to the working proper, and at the same time the length of the advancing is not subjected to a change.

Abstract: The driving gear meshes with the gear on the web of a planetary gear. This planetary gear includes an arrestable sun wheel. The output sun wheel is rigidly connected to the drive shaft. It extends through a sleeve section of the web. A longitudinally displaceable shifting sleeve is located on the sleeve section, which shifting sleeve has a plurality of control disks. These control disks control via a roller the rocking movement of the upper feeding roller. Accordingly, the period of the rocking movement can be selected depending on a respective selected control disk. If the sun wheel is unlocked, the shifting sleeve may be moved such that it engages directly the drive shaft such that by properly selecting the number of teeth it is possible to choose between a rotational speed transmission relation of 1:2 and 1:1.

Abstract: A needle thread feeding assembly in which the thread is positively fed at a desired stitch pitch while being clamped in between a presser roller and a drive roller, whose rotation is frictionally transmitted from a drive source. An encoder detects a predetermined amount of rotation and signals to restrict the drive roller, while allowing the drive shaft to continue rotating. A main-shaft-angle-detector detects predetermined angles adapted to operate the required stitch pitch and to start counting of pulses at the encoder. When a required number of pulses corresponding to the stitch-pitch is counted, the encoder signals to restrict the drive roller. Thus, the needle thread is positively and intermittently fed according to the stitch pitch.

Abstract: A tape feeding apparatus is provided for preventing the feeding of successive strips of tape unless and until the manual activator for the tape feeding mechanism has been allowed to return to its manual in operative position. There is a tape feeding apparatus, a drive apparatus for driving the tape feeding apparatus, and a clutch interposed there between.
