Abstract

Apparatus for cooperatively moving a plurality of guides for continuous filaments relative to spools upon which they are being wound to insure winding in even, successive layers. Spindles carrying the spools are mounted in parallel arrangement in a plurality of horizontal rows. A single, ball bearing screw is mounted with its axis vertical and carries a traveling member connected to an articulated arm. A linkage arrangement transmits reciprocating motion from the traveling member, through the arm, to a plurality of shafts, each carrying a guide element arranged adjacent one of the spools. The individual threads each pass over one of the guide elements to be moved thereby back and forth along the spool while being wound thereon. A selectively positionable switch arrangement allows adjustment of the limits of travel of the linkage, and thus of the guide elements. Means for adjustably positioning pairs of coaxial guide-carrying shafts are also disclosed, thereby doubling the capacity of the apparatus.

Claims12

Dependent claims

Apparatus for simultaneously controlling the level winding of a plurality of continuous filaments on separate spools, said apparatus comprising, in combination:

a. a plurality of spindles having parallel, horizontally disposed axes, each adapted to support a spool for winding a continuous filament thereon;
b. drive means for imparting rotation to each of said spindles;
c. a plurality of shafts mounted for reciprocal axial movement, one of said shafts being mounted laterally adjacent and parallel to each of said spindles;
d. a thread guide carried on each of said shafts and having a peripheral groove perpendicular to said axes;
e. a single, elongated, rotatably mounted, threaded member;
f. a traveling member engaged with said threaded member for reciprocating linear movement in response to rotation of said threaded member;
g. a motor for imparting rotation to said threaded member;
h. linkage means connecting said traveling member to each of said shafts to transfer said reciprocating linear movement from said traveling member simultaneously to each of said shafts for effecting said reciprocal axial movement of said shafts;
i. said plurality of shafts including at least one pair of shafts extending in coaxial alignment with one another, each of said pair being arranged laterally adjacent separate ones of said spindles;
j. means mounting said pair of shafts for relative axial adjustment;
and
k. means for releasably fixing the relative axial positions of said pair of shafts.
