A die-base ring (11) has at its upstream end a tubular ring (12) provided with a collar (12a) and co-operating with means for fixing the ring to a support (1). The fixing device includes four radial screws (19), pressing against a cylindrical bearing surface (13) of the support and making possible a mechanically operated off-centering of the ring relative to the support, and a clamping collar (20) making it possible to place two cylindrical bearing surfaces (14 and 15) in strictly coaxial positions. Axial screws (16) pass through the support with sufficient radial play to allow the adjustment.

Extrusion equipment for coating wire

A double winding machine for winding wire on reels includes two reel supports with drive shafts. Each support is equipped with a snagging mechanism comprising a hook-bearing disk with hook, an uncoiling member, and a bearing for supporting the disk and the uncoiling member coaxially with the reel and for allowing relative displacement of the disk and uncoiling member between an initial and a displaced position. A disengageable coupler is provided to rotationally couple the disk, uncoiling member and reel. The coupler can be translationally disengaged. Brakes are provided for the disk to produce a lag between the disk and reel to lengthen the leading end of the wire. The relative displacement is performed with the lag, allowing the leading end to be retained in the hook and uncoiling member. The leading end is thus made accessible, even after winding is complete.

Double wire-winding machine with automatic transfer

An installation for treating metal wire, such as for coating a copper conductor, comprises at its upstream end a stationary wire-supply source having a reel support disposed within a loop-guard made of a gray iron or ductile cast-iron part in the form of a hollow body of revolution having an ogival profile. This part bears at its downstream end a conical tip defining the exit aperture for the wire. The inner surface of the loop-guard is machined by turning so as to be absolutely smooth and may also be subjected to a hardening treatment.
