Abstract
Abstract Apparatus for winding a flexible strip or length of material into a coreless spiraled roll and including three sets of belts which are driven in corresponding directions through associated loop paths of travel, two of the paths generally paralleling each other and the third path crossing the other two paths at a variable angle. The strip of material is fed into a variable size winding space or cavity defined by the belts, and driven movement of the belts roll, form or wind the strip of material into a coreless spiraled roll thereof.

Claim 3
Dependent Claim
47 words
Apparatus in accordance with claim 1 and further including latching means for normally holding said first set of belts in said first loop path of travel and actuable to an unlatched condition for lowering such set of belts for removal of a completed roll of said material.
Claim 4
Dependent Claim
395 words
Apparatus for winding a strip or length of flexible ribbon material into a spiraled roll and without the use of a core member, such apparatus comprising, in combination; I. a main support frame including a pair of spaced-apart upright support plates; II. a first longitudinal frame member including a pair of side members supporting a first set of flexible and spaced-apart parallel belts for movement through a closed loop paralleling such side members, such frame member normally supported between said support plates for movement of the set of belts thereon through a first selected loop path of travel between such support plates; III. a second longitudinal frame member including a pair of side members supporting a second set of flexible and spaced-apart parallel belts for movement through a closed loop paralleling such side members, such second frame member supported between said support plates for movement of the set of belts thereon through a second selected loop path of travel between said support plates and initially paralleling said first selected path of travel with the outer surfaces of said second set of belts facing the outer surfaces of said first set of belts, a first end of such second frame member movable between said support plates away from and towards a corresponding first end of said first frame member; IV. a third longitudinal frame member including a pair of side members supporting a third set of flexible and spaced-apart parallel belts for movement through a closed loop paralleling such side members, such third frame member supported between said support plates for movement of the set of belts thereon through a third selected loop of travel between said support plates and initially crossing said first and second paths of travel at a selected angle thereto and with the belts of such third set thereof extending through the spaces between the belts of the first and second sets of belts to define a winding cavity, one end of such third frame member movable between said support plates away from and towards the second ends of said first and second frame members; V. means for driving said sets of belts in corresponding directions through their respective selected paths of travel between said support plates; and VI. means for guiding the leading edge of said strip of ribbon material into said winding cavity for winding thereof into said spiraled roll.
