Abstract
The present invention embraces a winder method and apparatus for collecting linear material such as glass strand into a wound package. The winder has a rotatable collet of a first material and a second material positioned on the collet. The second material has a coefficient of friction sufficient to engage the strand and to bring the strand into fixed engagement with the collet upon the rotation of the collet.
Claims4
A winder for making wound strand packages comprising:
- a. a rotatable collet with a circumferential catch groove arranged at the end of the collet, the end region of the collet comprising at least one cleaning aperture opening axially outwardly and extending as far as the bottom of the groove;
- and
- b. a plurality of bands of material, the bands comprising closed loops which are expandably stretched over the end region of the collet such that a portion of the bands extends along at least a portion of the catch groove so that a strand entering the catch groove becomes entangled with the bands, the circumferential groove being free from the bands in the region of the cleaning aperture.
A winder for making wound strand packages comprising:
- a. a rotatable collet with a circumferential catch groove arranged at the end of the collet, the end region of the collet comprising a plurality of cleaning apertures distributed over the circumference of the end region of the collet;
- and
- b. a plurality of bands of material, the bands comprising closed loops which are expandably stretched over the end region of the collet such that a portion of the bands extends along a portion of the circumferential catch groove and exits via adjacent cleaning apertures to form the loop so that a strand entering the catch groove becomes entangled with the bands.
A winder for the collection of a strand into a wound package comprising:
- a. a driven rotatable collet with a circumferential engagement groove which is positioned in the end region of the collet and at least two cleaning openings distributed over the circumference of the end region of the collet;
- b. a plurality of bands of material extending along the engagement groove over part of the circumference thereof to engage a strand inserted into the groove, the bands of material comprising closed rings tensioned over the end region of the collet such that a portion of each band extends along the engagement groove and extends out from and into the groove through adjacent cleaning openings so that the rest of each band is located outside the engagement groove.
