Abstract

A sleeve type lap creel has two outer sleeve sections (1, 2) and an intermediate sleeve section (3) arranged in axial alignment with one another. The outer sections form substantially hollow cylinders. The intermediate section is formed by carrier ribs (8, 9) extending axially from each outer sleeve section toward the other sleeve section. The carrier ribs are circumferentially spaced so that the ribs of one outer sleeve section fit between the ribs of the other outer sleeve section. Initially, the ribs (8, 9) are fully extended and interconnected, for example axially or in the circumferential direction by frangible bridges (15). By pushing the outer sections toward each other the frangible bridges are broken and the ribs of one section move into the other section and vice versa. The ribs have projections (16) which fit into recesses (17) of the sleeve sections for arresting the ribs in the sleeve sections in a plurality of different positions, whereby the length of the lap creel is changeable. Both sections with their ribs can be made in the same mold.
