Abstract
Apparatus for winding at least one strip of an elongate product, such as a wire or ribbon, on to a cylindrical body from a spool of the product comprising means for producing relative rotation of the spool around the cylindrical body, a main drive unit for driving the rotation producing apparatus and connected to the axle of the spool through a differential driven by a secondary drive unit for braking the spool to tension said product. The secondary drive unit may be controlled by the output of a tension sensing mechanism sensing the tension of the product.
Claims3
Apparatus for winding at least two strips of an elongated product under tension onto a cylindrical body each from a spool holding a supply of product, said apparatus comprising,
- a frame displaceable longitudinally along the cylindrical body,
- a ring fixed to said frame and coaxially surrounding the cylindrical body,
- a first support turret supporting said spools, each spool being rotatably mounted on said turret around a respective fixed axis on said turret,
- second and third control turrets for controlling the unwinding of each respective spool, said second and third turrets each including a gear toothing,
- a pinion drivingly coupled with each spool and in mesh with the gear toothing of a respective one of the control turrets,
- roller bearing means rollably supporting the turrets on said ring for relative rolling movement around the cylindrical body,
- a main drive motor means for driving each individual turret around the cylindrical body,
- a differential drivingly coupling said main drive motor means and each said control turret, said differential including pinion gears, and
- auxiliary motor means for independently driving the pinion gears of said differential to control the tension of the strip.
