Abstract
A device for endless coiling of strip material has a support and two coil drums which are spaced from one another and move synchronously along the support in opposite directions. The first and second coil drums are displaced alternately to an initial position, wherein each of these drums rotates to receive a leading edge of a respective coil of strip material. Thereafter, each of the coil drums is displaced to a respective finish position where the coil drums each receive the remainder of a respective coil. The finish positions are spaced from the initial positions in opposite directions. The first and second coil drums are displaced alternately to a coil removal position, at which a respective wound coil of strip material is removed from each of the coil drums.
Claims19
A device for endless coiling of strip material to form a plurality of coils, each coil having a respective leading edge and trailing edge, the device comprising:
- a support;
- first and second coil drums spaced from one another on the support and displaceable together in opposite directions along the support such that displacement of the drums in one of the directions moves the first drum to a first initial position and moves the second drum to a respective second finish position spaced from the first initial position, and displacement of the drums in the opposite direction moves the second drum into a second initial position and moves the first drum to a respective first finish position spaced from the at least one initial position;
- each of the first and second drums being rotatable to receive the leading edge of a respective coil while the drum is in the respective first or second initial position and to continue winding the coil in the first and second finish positions of the drums, respectively;
- the first and second coil drums being alternately displaceable from the respective first and second finish positions to a respective first and second coil removal position, at which a respective wound coil of strip material is removable from the respective one of the first and second coil drums.
A method for endless coiling of strip material comprising the steps of:
- (a) winding a leading edge of strip material on to a first coil drum which is in a first initial position;
- (b) displacing the first coil drum in a first direction to a first finish position, and there winding a length of the strip material which follows the leading edge on the first coil drum;
- (c) cutting the strip material after the length of the strip material has been wound on the first coil drum, thereby forming another leading edge of the strip material;
- (d) simultaneously with step (b), displacing a second coil drum, which is spaced from the first coil drum, in the first direction to a second initial position, and there receiving the other leading edge of the strip material;
- (e) displacing the first and second coil drums in a second direction opposite the first direction to move the first drum to a first coil removal position, and there removing the wound strip material from the first coil drum, and to displace the second coil drum to a second finish position, and there winding a length of the strip material which follows the other leading edge on the second coil drum;
- (f) displacing the first and second coil drums in the first direction to bring the second drum to a second coil removal position, and there removing the wound strip material from the second coil drum.
