ABSTRACT:
An apparatus for providing a continuous supply of web material to a web printer or other system. The web material is fed from a first roll supported in a feed position, and when the first roll is near depletion, the leading end of a second roll is adhesively connected to the web of the first roll with that web then being severed. One belt drive means is employed for rotating both the forward and rearward rolls so that these achieve the same speed for the connecting and severing operations. The belt drive means are connected to the press drive through control means which vary the belt drive speed in accordance with the tension of the web. An indexing conveyor supports forward and rearward rolls to locate the rolls in the forward and rearward running positions and in intermediate positions for connecting and severing of the web material and for loading of new rolls into the system.
