- 1. A method to continuously unwind a web of material by splicing replacement rolls of material thereto without stopping the unwinding operation comprising the steps of: unwinding a roll of material, placing a replacement roll of material above the roll of web material being unwound, placing a strip of double-side adhesive tape to the surface of the tail of the replacement roll of web material on the side of the tail which faces the roll of web material, applying a suction pressure to the tail of the replacement roll of web material and moving the tail to a position adjacent the roll of web material being unwound, maintaining the suction pressure on the tail until the roll of web material being unwound is almost exhausted, transferring the tail of the replacement web material to a perforated roll by releasing the suction pressure thereon and exerting another suction pressure thereon through the perforated roll and rotating the perforated roll to move the tape into engagement with the web of material of the roll being unwound to splice the replacement roll of web material thereto to allow the unwinding operation to continue uninterrupted.
Parent Case Info
This is a division of application Ser. No. 229,253, filed Aug. 8, 1988, for Laminator Unwind Roll Stand, now U.S. Pat. No. 4,832,272.
This invention relates to an efficient unwind roll stand which allows easy and efficient replacement of an exhausted fabric roll supplying fabric to another point of use such as a lamination machine.
Unwind stands for material such as paper, fabric, etc. have been known for years but replacement of an exhausted roll of material in a continuous operation has always been a problem. First the old, almost exhausted roll of material has to be attached to the new supply of material and then, when the new material has been placed in communication with the material consuming machine, the shaft and/or roll of the exhausted material must be removed from the unwind machine.
Therefore, it is an object of the invention to provide a new and novel material unwind stand which provides ready replacement of an exhausted supply of material with a new supply of material.
