Bobbin for the reeling of skein-like material and method of manufacture of the said bobbin

摘要

The invention relates to a bobbin for the reeling of skein-like material, which bobbin has lateral discs or flanges, which are creased or corrugated for reinforcement. Each corrugation or crease is formed by individual segments (25) which are of the same shape and dimensions. The individual segments (25) are placed next to one another in a row in the circumferential direction, leaving a gap (33) at the joints if necessary and are fixedly connected, especially welded, to the running mark (3 or 4) and the cylindrical core support (5). The lateral discs may also consist of two sets with segments of the same shape and dimensions in each set. The individual segments can be produced in each case with great accuracy and can be precisely allocated to one another, so that the points to be welded once the segments have been lined up next to one another in a row are clearly determined. By these means, welding robots can be used in welding, which results in uniform products and a saving of production costs. <IMAGE>
