Abstract
An apparatus for unwinding a roll of web material which is prone to blocking: for example, an elastomeric film which, while rolled, is prone to having the convolutions of the roll stick together. The apparatus induces a sufficiently high rate of strain in a short span adjacent the roll to effect continuously peeling the outermost convolution from the roll. Additionally, the apparatus is of such a geometry that, in the event blocking precipitates circumferential shifting of the point of web separation from the roll, the stripping angle is increased. This, in turn, increases the effectiveness of the rate of strain induced peeling force on the web whereby more positive peeling occurs.
