Coiling device
First Claim
1. A device for coiling and uncoiling of elongated goods onto a drum comprising:
- a support having a driving device, and a spreader arm configured to be driven by said driving device, said spreader arm being rotatably mounted on the support and when driven by the driving device being configured to coil or uncoil the elongated goods onto the drum, when said drum is stationary, where a coiling operation occurs when said spreader arm is driven by said driving device in one direction, and an uncoiling operation occurring when said driving device drives the spreader arm in an opposite direction, wherein said spreader arm having a gripping arm positioned to face the elongated goods and configured to guide the elongated goods substantially in a tangential direction relative to a periphery of the drum.

Abstract
A device for coiling and uncoiling elongated goods (K), such as wire, cable or the like, onto a drum (13) comprises a support (12) with driving means (25) for a spreader arm (10). The spreader arm (10) is rotatably mounted on the support (12) and supports a gripping arm (14) for coiling and uncoiling the elongated goods (K) onto the stationary drum (13). The gripping arm (14) is formed as a curved V-profile having a running track arranged for the elongated goods (K), which running track is oriented towards the drum (13). The said running track is defined by feeding rollers mounted within the gripping arm (14). The feeding rollers are spherical in shape and have a rolling resistance near zero to eliminate twisting of the elongated goods (K) during coiling and uncoiling. The device also comprises a lifting and rotating table (15) provided under the drum (13) for making possible 180° rotation of the drum (13), which has a coupling (16, 27) to the support (12) detachably arranged during lifting of the drum (13).
