发明名称 Method and means for winding helical coils from thermoplastic materials
摘要 A method of and means of winding close wound helical coils of a thermoplastic monofilament material is proposed wherein, in order to avoid secondary twist in the resultant coil, the coil, after having been wound and heat set under controlled conditions on a first part of a mandrel, is twisted in a direction tending to close the individual turns of the coil during the cooling thereof while passing along and/or from the end of a second part of the mandrel to a twist arresting means arranged in spaced apart disposition relative to such end.
