ABSTRACT:
The invention relates to a lap creel made of rod shaped carrying members (1) which form, together with ring shaped fixing elements (2-6) a circular cage. The carrying members (1) project radially outwardly across a portion of the fixing elements (2-6). A fixing element (2) arranged at one end of the lap creel, has inwardly opening grooves (10), the number of which corresponds to the number of carrying members (1). Through these means the appropriate end of the lap creel receives a free-space inner cross-section which corresponds to the outer cross-section of the opposite end of the lap creel. The outer surfaces (7) of the carrying members (1) form parts of a shell which is shaped so that an imaginary enveloping of the lap creel in the central region has a contraction (8). The lap creel thus receives a bi-conical shape; that is, a shape which occurs if two truncated cones at the smaller of the end face diameters are arranged end to end. With the lap creel according to the invention, the lower portion with larger diameter may also be shaped almost cylindrical.
