ABSTRACT:
The device disclosed serves to splice the trailing end of packaging strip wound off a used-up roll to the leading end of a new roll, and comprises heated pressure rollers that bond the two ends of the strips, plates that guide the leading end of the new strip about to be bonded, and a sensing wheel that detects proximity of the leading edge of a new strip when fed into the guide plates. The trailing end of the used-up strip is cut by a blade located upstream of the guide plates, and a timer is used to set the operating time lapse of the pressure rollers according to the length of the splice as established by the stroke of the blade.
