Abstract
A method and device for everting flexible tubular members, such as food casings and the like, is disclosed wherein a tubular member is axially displaced by a frictional engagement means, which means is deposed in a distal end portion of the member, and which frictionally engages the interior surface of said member and displaces said member to a point where the member is folded back over itself (everted) and then displaces said everted member, from the point of everting over the exterior surface of the noneverted tubular member.
Claims28
A device for everting a flexible tubular member or the like comprising frictional engagement means insertable into a distal end portion of said tubular member to frictionally engage the interior surface thereof to axially displace said tubular member to a point of everting, and means for displacing everted tubular member from the point of everting over the exterior surface of the noneverted tubular member.
A method for everting a flexible tubular member comprising frictionally engaging the interior surface of said tubular member, axially displacing said member to a point of everting by means of said frictional engaging, everting, and displacing everted tubular member from the point of everting over the exterior surface of the noneverted tubular member.
Everted flexible tubular member formed by a method comprising frictionally engaging the interior surface of an unshirred noneverted tubular member to a point of everting, everting and displacing everted tubular material telescopically from the point of everting over the exterior surface of the noneverted tubular member.
