ABSTRACT:
A winding drum (8) for forming the storage coils has pins or ribs (11) extending substantially in axial direction of the drum.
In a known winding drum the ends of the pins where the thread coil leaves the drum slightly converge towards the drum axis, thereby forming a conical drum part. According to the invention at least some pins (11b) are parallel to the drum axis which prevents the coil to leave the drum (8) too abruptly, so that the release pattern of the coils is more uniform.
