Abstract
The invention relates to control of the cut end of a fabric web during batching and doffing thereof to provide positive engagement of the cut end with a new mandrel after cutting. Included herewith is a tucking mechanism rotatable into and out of engagement with the bite between a winding roll and an empty mandrel which provides simultaneously positive pressure against the web during the first several windings on the empty mandrel with tucking engagement of the loose end of the web into the bite. The tucking mechanism includes a transverse bar receiving a plurality of reversible holders which are displaceable along the transverse bar for accommodating different widths of fabric. The holders contain opposed tucking feelers of different lengths for differing fabric characteristics.
