METHOD FOR INCREASE THE LENGTH OF USE OF A SCROLLABLE LAYER BY UNROLLING THE ENTIRE LAYER WRAPPED AROUND A CORE

Machine to join ends of reels of plastic strip - presses previously glued end of new reel to end of old reel

Machine for joining end of a moving reel of tape to end of a new, stationary reel. The machine comprises two similar reel supports, and a device to press one piece of tape against the other. The passage of the end of the old reel of tape is sensed by a sensing device. This actuates a pivoting lever which presses the end of the old reel against the start of the replacement, stationary reel, previously glued. The end of the new reel is thus pulled free of its retaining clips and drawn out as required. The retaining clamps are pivoted upwards for insertion of the tape ends, and downwards again before use. The tape is suitably tensioned before joining. The whole machine is mounted on rollers and guides to permit lateral movement.

Web splicing apparatus

WEB SPLICING APPARATUS ABSTRACT OF THE DISCLOSURE A splicing head for an automatic zero-speed web splicing machine is disclosed in which the end of a new roll of web material can be prepared for splicing directly on resilient nip rollers which are used by the machine to perform the splicing operation. In particular, the splicing head includes a knife carriage through which the web material passes and which can be moved transversly to the web travel direction under control of a cam and lever arrangement to introduce a predetermined loop of slack into the web material. The action of the cam and lever mechanism also positions a serrated preparation blade mounted on cantilever arms in front of the nip rollers for squarely trimming the edge of the web material. After the web material has been trimmed the preparation blade can be moved by the cam and lever arrangement to an out-of-the-way position to allow preparation of the web material and to prevent interference with the splicing machine as the web material runs through the machine after the splice has been made.

Splice-in-register control

ABSTRACT OF THE DISCLOSURE A control system for a web-feeding machine used to provide a continuous supply of material having successive labels and registration marks printed serially thereon is disclosed. The machine has an assembly for splicing the material from a ready web and the material severed from a running web wherein the response of the assembly after being actuated is delayed by a response time T. The control system comprises a driving circuit having an input and an output electro-mechanically coupled to the splicing assembly actuated thereby in response to a signal applied to the input thereof, a scanner positioned adjacent the material to provide a signal in response to the presence of a registration mark, and an encoder for providing a fixed number of pulses proportional to a corresponding length of the moving material. The control system also comprises a control circuit connected to the scanner, the encoder and the input of the driving circuit. The control circuit counts the number of encoder pulses between successive scanner signals and then decrements from that number to zero and, responsive to a scanner signal, provides a time delay To preset to approximate the response time T and decrements to zero from a preset number D after the time delay To has expired. The control circuit also provides a splice signal SS and supplies a splice-command signal SC to the input of the driving circuit in response to the splice signal SS. The machine accomplishes a splice-in-register after the splice-command signal SC has been applied thereto.
