Abstract
A first and a second clamp member 25, 35 are shaped onto a coil former 1 to be provided with a coil and together with first and second clamping bodies 26, 36 permit the clamping and holding of the wire 10 during the winding and/or separation of the wire. For separating the wire 10 a separating apparatus 45 having a separating mandrel 46 and a separating sleeve 47 is placed on the coil former 1, so that the separating sleeve is moved relative to the separating mandrel and as a result the wire is separated. The winding apparatus can form a station C of an injection moulding machine on which it is possible to produce arc welded sleeves 4 made from thermoplastic material.
Claims7
An apparatus for forming a welding sleeve of the type having a coil of electrical resistance heating wire in spaced, juxtaposed turns embedded in the inner wall of a thermoplastic sleeve member and surrounding a cylindrical coil former, comprising
- means at opposite ends of the coil former defining first and second clamp members;
- means for winding the coil of wire around the former so that the windings extend from said first clamp member to said second clamp member;
- first and second clamping bodies;
- means for supporting said clamping bodies for movement toward and away from said first and second clamp members, respectively, so that said first clamping body can be moved to engage said first clamp member after the wire has been placed on said first member to attach the wire thereto, and said second clamping body can be moved to engage said second clamp member after the wire has been placed on said second member to attach said wire thereto;
- and
- means operatively associated with said second clamping body for severing said wire after attachment thereof to said second clamp member.
