Abstract
A hollow winding bobbin base (18) is constructed of a material having a relatively low thermal coefficient of expansion (e.g., quartz) and has a pair of flanges (32) slidably located on the ends. A metal tube (24) is received within the base (18) and has annular springs (40) on its ends urging the flanges (32) toward each other. An elastomer baselayer (30) is fitted onto the outer surface of the base (18).
Claims8
A winding bobbin for supporting a wound filament pack while providing stress compensation within the wound pack, comprising:
- a base constructed of a material having a thermal coefficient of expansion less than metal with the base having an outwardly facing peripheral surface and a longitudinal axis extending throughout;
- a baselayer constructed of a compliant material and supported on the peripheral surface of the base;
- first and second flanges located on opposite end portions of the base layer for retaining the wound pack therebetween;
- means mounting the flanges for limited movement generally parallel to the longitudinal base axis;
- and
- spring means engaging a surface for each flange for resiliently urging said flanges toward one another, thereby maintaining the flanges in contact with the wound filament pack.
