Definitions
- the twisting drum 107 is driven through a gearwheel 103 which is constructed on the end flange 160.
- the ratio of rotary speeds of the gearwheels I02 and 103 determines the ratio between the speed and twisting of the wire 29.
- the wire 29 which is fed by the feed rollers I00 and which is simultaneously twisted is pushed by wire guides 105 disposed inside and outside the twisting drum I07 against winding pins I06 and is consequently bent to form spring coils.
- the part of the mahcine shown in FIG. 2 in order to avoid an inelastic torsion deformation of the portion of wire fed to the twisting apparatus in FIG. 1, operates in the following manner:
- any difference in the twisting speed which may exist is determined by the number of rotations of the twisting drum 107, which this drum I07 would perform during the stoppage time required for cutting off wire 29, that is if it were to continue running. This difference in number of rotations ensures that the further rotation of the reel flange 48 occurring during stoppage of the twisting drum 107 results in a complete relaxation of the spring wire 29.
- Winding machine wherein the drum is freely rotatably mounted on a hollow shaft receiving the spring wire and comprising a first bevel gear mounted on the hollow shaft, the first bevel gear meshing with a second bevel gear affixed to the shaft of one of the rollers.
- Winding machine according to claim 3, wherein the drum has an end flange which is constructed as a gear wheel.
- Winding machine comprising a reel carrying a bundle of wire from which the spring wire is fed, the reel being constructed as an overhead reel. and comprising a second pair of loose guide rollers located on the overhead reel and clamping the spring wire. thereby lockingly holding it against rotation relative to the two loose guide rollers.
- Winding machine according to claim 5, wherein the second pair of rollers are jointly rotatable about the axis of the portion of wire which is located in the region of them.
- Winding machine according to claim 5, wherein the overhead reel is drivable and is mounted to rotate about the axis of the bundle of wire.
- Winding machine comprising an arrangement for the equalization of the imbalance of the reel which normally occurs as the wire is unwound from the bundle.
- Winding machine according to claim 5, wherein the portion of wire between the second pair of rollers and the bundle of wire is maintained free from plastic deformation.
