Abstract
A roving frame apparatus and method for winding roving upon bobbins (A) and doffing full packages directly upon a conveyor (F) wherein a spindle rail (C) is moved laterally beneath an overhead conveyor removing full packages therefrom and supplying empty bobbins thereto.
Claims5
A roving frame having a spindle rail and flyers in vertical alignment therewith comprising:
- a movable conveyor;
- a plurality of longitudinally spaced doffing means having a bobbin receiving receptacle carried by said conveyor;
- a drive mechanism including a transfer drive moving said rail to a doffing position out of vertical alignment with said flyers;
- a vertical traversing drive moving said rail upwardly in respect to said conveyor when in doffing position;
- and
- an indexing drive moving said conveyor and said doffing means carried thereby longitudinally in increments in respect to said rail.
The method of making roving utilizing a drafting system for attenuating a sliver strand and a transversing spindle rail carrying spindles upon which roving is distributed from flyers comprising the steps of:
- moving said spindle rail downwardly and rearwardly toward a source of textile strands to a doffing position back of said flyers;
- and
- providing a transport device above said spindle rail when in said doffing position;
- said rail when in said doffing position being in alignment with said transport device for reception of full bobbins thereby directly from said traversing rail.
