Abstract: Device and method for constant tension feeding, threads or yarns fed to textile or winding machine or metallic wire to similar machine, in discontinuously with phase sequences. The thread motion has at least first and second feeding or absorption states following each other in time. A controller, connected to a tension detector and thread accumulator, intervenes on the accumulator based upon tension value from the detector. A compensator, between the accumulator and tension detector, cooperates with thread to compensate variation of feeding or absorption state of the thread upon passage between each first and second feeding or absorption state. The controller intervenes to modify the accumulator's action on thread and maintain tension value detected by the detector at set value. Interaction between thread and compensator keeping constant tension value during the changing phase of the feeding state. The compensator freely moveable under action of thread relative to a resting position.

Abstract: The present invention provides for safe and simple replacement or removal of individual feeders from a placement machine without any loss in performance by using a signal means to emit a signal to the CPU of the placement machine when a feeder is removed. Upon receipt of this signal, the CPU controls the pick-up head in such a way so that it does not collide with the feeder being removed. If the pick-up head is located directly above the pick-up position of the feeder to be removed, it can be moved momentarily upwards or sideways thanks to its fast drive before a collision occurs. If the pick-up head is located just on the way to the pick-up position of the feeder, the procedure is momentarily aborted so that a collision can be avoided.

After each indexing step, the shutter is moved away from the pick-up area in order to provide access to the component in the opened pocket.

Abstract: It is convenient to supply electrical or electronic components for placement on tapes; however it has proved difficult to satisfactorily handle tapes for carrying large components. Use of wide tapes to feed larger components is facilitated by using a drive belt (48) to rotate at a sprocket wheel (44) to feed the tape (38,40), a drive wheel (52) to move the belt, and drive means conveniently a ratchet wheel to cause the drive wheel (52) to rotate through a predetermined angle to feed the tape a distance equal to the spacing between the components on the tape. Wide tape can conveniently be disposed of after unloading by using means (88,90) for severing the tape (38) immediately downstream of an unloading position, and means for collecting the severed tape preferably comprising a duct (84) through which a current of air flows to carry the severed tape to a remote receptacle (85).

The apparatus is arranged to separate a covering tape from a tape base of the carrier tape only at a position directly below a vacuum chuck for picking up the component, while the covering tape is separated from the tape base so as to be wound up at a winding speed lower than an intermittent feeding speed of the carrier tape by a predetermined pitch.

Abstract: The input shaft of a punch press is rotated at a continuous preselected speed and is drivingly connected by a cam drive mechanism to an output shaft to generate oscillating rotational movement of the output shaft. Upper and lower feed rolls are rotatably supported in a frame in overlying relation to engage stock material extending between the upper and lower rolls. A combination linkage and gear cluster transmits the oscillating rotation movement of the output shaft to one of the feed rolls. The second feed roll is pivotally supported in the frame for movement toward and away from the first feed roll. A coupling drivingly connects the gear cluster to the second feed roll to oscillate the second feed roll through an angle of rotation corresponding to the angle of rotation of the first feed roll and thereby drive both of the feed rolls to intermittently feed a preselected length of the stock material to the press.

Abstract: An array of dancer rollers are resiliently biased for engaging a plurality of webs in a take-up zone of a honeycomb machine. The dancer rollers engage each web and thrust it out of its plane of advance to maintain the webs under continuous tension loading as they are alternately advanced and halted during successive feeding and cutting cycles, respectively. A pair of index rollers engage the webs, pull them from supply rolls and feed them to a cyclic cutter in response to rotation of the index rollers. In this arrangement, the continuous drive rollers used in conventional web movement arrangements are eliminated with the webs being pulled from the supply roll intermittently and according to need by the index rollers.

Several banks of stacked servicer modules may be mounted on a shuttle module for multistation operation. Each servicer module has provision for supporting stock and liner take-up rolls and includes fixed and hingedly mounted component dispensing trays which when the modules are arcuately stacked, are all located proximate the tire building drum for application of components thereto.

Abstract: In a tape recorder in which a pinch roller is pressed against a motor-driven capstan to move a magnetic tape at a constant speed, a pause device includes an actuator connected to a pinch roller carrier to stop the tape movement by separating the pinch roller from the capstan. Continued movement of the actuator to an over-stroke position latches a switch controller to the actuator, and release of the actuator to an intermediate position draws the switch controller with it to allow a switch in the power supply circuit of the motor to open, stopping the motor after the tape has stopped. Restarting from the paused condition involves moving the actuator to the over-stroke position to release the switch actuator, then allowing the actuator to return by spring force to the unactuated position to allow the pinch roller to resume pressing the tape against the capstan.
