Abstract

The machine for winding continuous electric windings comprises a framework supporting thereon a carriage movable along the framework and having an annular housing. Mounted inside the housing is an annular rotatable base having mounted thereon members for placing the wire being wound. Mounted on the end portion of each wire-placing member is a driving roller movably engaging a friction templet mounted on the annular housing. The movement of the driving rollers along the friction templet provides for movement of respective the wire-placing members in the direction toward the coil section being wound. The opposite end portion of each of the wire-placing members supports an additional guiding member made in the form of a roller and designed for feeding the wire into the winding zone.

Claims

1. A machine for winding continuous electric windings without changing the position of the winding sections, comprising:

a framework;

a first stock supported by said framework;

a second stock supported by said framework and being coaxial with said first stock;

a first center fastened externally of said first stock;

a second center fastened externally of said second stock;

a winding mandrel supported between said first and second centers;

fixing members mounted on said first center;

a sliding spindle mounted on said second stock for axial movement of the second center;

a carriage movable along the axis of said centers;

an annular housing supported by said carriage;

a rotatable annular base accommodated within said annular housing;

a plurality of wire-placing members fastened to said rotatable annular base and movable in two perpendicular directions, said wire-placing members having a first end and a second end;

an additional guiding member mounted on said first end of each of said wire-placing members to guide said wire into the winding section being wound;

a friction templet mounted on said annular housing;

a driving roller mounted on said second end of each of said wire-placing members and traveling in engagement with said friction templet; and

means accommodated within said driving roller to transmit rotation from said driving roller to the respective one of said additional guiding members.

2. A machine as set forth in claim 1, wherein each of said additional guiding members is rubber-coated.
