ABSTRACT:
A winding apparatus for winding webs of paper, textile fabric, synthetic plastic material or other similar webs into tight rolls comprising a winding chamber having an inlet opening at the top and a pair of drive rollers for frictionally driving a roll of material arranged at the bottom, substantially diametrically opposite the inlet opening. One side of the winding chamber is defined by concave surfaces of a plurality of parallel wall elements, and the other side of the winding chamber is defined by a pivotally mounted shell body. In preferred embodiments, alternate devices for fastening a wound roll with an adhesive strip are disclosed. The winding apparatus of the invention can be manufactured at reasonable cost, does not require excessive space, and functions with a high degree of reliability.
