<p>METHOD AND APPARATUS FOR STRIPPING A CONTINUOUS WEB OF MATERIAL FROM THE MARGINAL EDGE OF A BODY An apparatus for use in stripping a continuous web of severable material from at least along a portion of the marginal edge of a body comprising supporting means having a receiving surface upon which the body with the continuous web is advanced along a predetermined path. The apparatus embodies deflecting means pivotally connected to the supporting means for assisting in directing the leading edge of the advanced continuous web vertically so as to facilitate a stripping thereof while permitting travel of the body along the path. Stripping means including a pair of generally longitudinal and cooperating rollers are contemplated as being connected to the supporting means and positioned along the path for grabbing therebetween the vertically deflected continuous web and stripping it from the body in response to the advancement of the body along the path. Also, envisioned are advancing means operatively connected to the supporting means remote from the stripping means for automatically continuing the advancement of the body by pulling the body past the rollers along the path for ensuring complete tearing apart of the web from the marginal edge. The method enables the continuous web to be severed from at least along a portion of the marginal edge of the body and comprises the steps of feeding the body in a first direction along a predetermined path, vertically directing the leading edge of the advancing web so as to facilitate a stripping thereof, stripping the deflected continuous web by cooperating rollers as the body continues to advance in the first direction such that increasing portions of the web become gradually separated from the body by the rollers and automatically continuing advancement of the body along the predetermined path by pulling the body past the rollers such that complete severance of the web from the marginal edge of the body is accomplished.</p> |
