Abstract:

A method and apparatus for forming spiral wound rolls from strips of compressible material uses a first endless belt conveyor to deliver the strips of compressible material into a winding space. As the strip enters the winding space, the strip is compressed by a compression and slider plate to the desired thickness for the layers of strip material in the spiral roll. Then, the leading portion of the strip successively contacts: an inclined, second endless belt conveyor, a compression roll, and a third endless belt conveyor which together with the first conveyor define the winding space. The second conveyor extends upwardly at an acute angle to the first conveyor and as the strip of compressible material contacts the second conveyor it maintains the strip in compression and starts to turn the strip back upon itself to form the spiral roll. The strip next contacts the compression roll which is located intermediate the first and second conveyors. The compression roll continues to turn the strip back upon itself and maintains the strip in compression.
