<p>The invention relates to a winding spool, made of two spool bodies stuck to each other, which has a cylindrical reel barrel and two lateral spool flanges, the abutting surfaces extending radially, preferably, in the middle of said winding barrel. Said winding spool also comprises adhesive tongues, which are formed on said abutting surfaces and engage into corresponding insertion pockets of the other respective spool body. The aim of the invention is to optimally design the joining area of both spool bodies, in order to provide the rotational accuracy as well as to avoid edges and deformations in said joining area. Said aim is achieved, whereby the winding spool is deigned, such that the spool bodies are joined to each other positively or non-positively and the application force, which acts on the contact surfaces, is increased. The adhesive tongues, projecting from said abutting surfaces, extend in the shape of a semicircle and the insertion pockets have corresponding shape. Moreover, said adhesive tongues have flattenings on the free ends thereof and said insertion pockets have corresponding inner areas. Said winding spool is particularly suitable for winding components for producing electronic components.</p> |
