Abstract
A multiple winding machine for winding lace bands or similar type fabric material onto cores uses a plurality of cup-like guides through which the lace bands pass. The guides are positioned horizontally and vertically with respect to each other so as to be aligned with a corresponding core onto which the lace band is wound. The guides move transversely in a back-and-forth path so that the lace bands wind on the corresponding cores in a uniform, tightly packed manner. Transfer rollers provide uniform tension to the lace bands while imparting uniform tangentional speed to the cores and lace bands as the lace bands are wound on the cores. A mechanism for determining improper removal of draw threads between adjacent lace bands is also disclosed so as to stop the machine if a faulty removal condition exists.
Claims45
A multiple winding machine for winding separated lace bands produced from a fabric web comprising:
- (A) a plurality of lace band guides, each lace band guide associated with one lace band, each lace band guide having an arcuately shaped surface over which a lace band passes, the plurality of lace band guides have a forward arcuate terminating end for receipt of the lace band and a rearward terminating end having a shallower arcuate shape for allowing the lace band to exit from the lace band guide in a relatively flat orientation;
- (B) means attached to the lace band guides for causing the lace band guides to move in a back-and-forth direction so as to impart a similar back-and-forth movement to the lace bands passing through each lace band guide;
- (C) at least one transfer roller, each transfer roller positioned in proximity to one or more lace band guides for pulling the lace bands through the lace band guides;
- (D) a corresponding plurality of cores, each core contacting a transfer roller so as to be turned when the transfer roller turns and so that a lace band attached to each core is similarly turned by the transfer roller;
- (E) means for maintaining the plurality of cores in frictional rolling engagement with the transfer roller;
- and
- (F) means for powering each transfer roller and means for causing back-and-forth movement of the lace band guides;
- whereby as each transfer roller turns, the lace band guides move in a back-and-forth path so as to cause the lace bands to wind about the cores in a similar back-and-forth path with each wound lace band being turned by a transfer roller.
A multiple winding machine as defined in claim 11 wherein the lace band guides are aligned in a plurality of horizontally positioned rows and further wherein horizontally positioned bars are spaced below the forward arcuate terminating end of the lace band guides associated with each horizontal row so that the lace bands contact a portion of the associated bar, thereby ensuring that the lace bands enter the lace band guides at the lowermost position of the forward end of the lace band guides.
A multiple winding machine for winding separated lace bands produced from a fabric web comprising:
- (A) means for pulling the separated lace bands away from the fabric web;
- (B) means for positioning the separated lace bands with respect to each other;
- (C) a plurality of lace band guides, each lace band guide associated with one lace band, each lace band guide having a generally cup-like shape having a forward arcuate terminating end for receipt of the lace band and a rearward terminating end having a shallower arcuate shape for allowing the lace band to exit from the lace band guide;
- (D) means attached to the lace band guides for causing the lace band guides to move in a back-and-forth direction so as to impart a similar back-and-forth movement to the lace bands passing through each lace band guide;
- (E) at least one transfer roller, each transfer roller positioned in proximity to one or more lace band guides for pulling the lace bands through the lace band guides;
- (F) at least one pair of channel members, each pair of channel members extending upwardly away from one transfer roller, each channel member defining a longitudinal path extending away from the transfer roller;
- (G) at least one support rod, each support rod associated with one transfer roller and positioned for axial rotation and movement along the longitudinal path of the channel members;
- (H) a corresponding plurality of cores removably mounted to the support rod, each core contacting a transfer roller so as to be turned when the transfer roller turns and so that a lace band attached to each core is similarly turned by the transfer roller;
- and
- (I) means for powering the separated lace band pulling means, each transfer roller, and the means for causing back-and-forth movement of the lace band guides;
- whereby as the transfer roller turns, the lace band guides move in a back-and-forth path so as to cause the lace bands to wind about the cores in similar back-and-forth paths with each wound lace band being turned by a transfer roller.

- (D) a corresponding plurality of cores, each core contacting a transfer roller so as to be turned when the transfer roller turns and so that a lace band attached to each core is similarly turned by the transfer roller;
- (E) means for maintaining the plurality of cores in frictional rolling engagement with the transfer roller, the means for maintaining each core in frictional rolling engagement with the transfer roller comprises at least one pair of channel members, each pair of channel members extending upwardly away from one transfer roller so as to define a longitudinal path extending away from the transfer roller;
- (F) at least one support rod, each support rod associated with one transfer roller and positioned for axial rotation and movement along the longitudinal path of a pair of channel members;
- wherein the cores are removably mounted to the support rod for frictional engagement with a transfer roller;
- and
- (G) means for powering each transfer roller and means for causing back-and-forth movement of the lace band guides;
- whereby as each transfer roller turns, the lace band guides move in a back-and-forth path so as to cause the lace bands to wind about the cores in a similar back-and-forth path with each wound lace band being turned by a transfer roller.
