  • Patent number: 10294065
    Abstract: A retainer is described for exerting a braking effect on wire provided as a spool in a container. The retainer has a plate-like elastic element with a contact surface adapted for resting on the wire, an outer circumference adapted for being guided in the container, and an inner circumference adapted for allowing the wire to pass through. The plate-like elastic element has an elasticity such that one of the inner and outer circumferences sags down, under the proper weight of the retainer, by a distance of at least 10 mm when the retainer is supported at the other of the inner and outer circumference.

  • Patent number: 9975728
    Abstract: A wire feeding system comprises a wire container including a box having an open upper side, and a wire container lid closing the upper side. The wire container lid includes a front wall having an opening through which wire is to be paid off. A wire outlet guide is attached to the front wall. The wire outlet guide comprises an upper and a lower hole for receiving the wire, the upper and lower holes being defined by a lower ring wall and an upper ring wall, respectively, and being distanced from each other in a wire feeding direction. At least the lower ring wall limits sideward movement of the wire and allows contact with the wire. The holes have a fixed position relative to the front wall. A deflection space bridging the distance between the holes allows sideward deflection of the wire between the ring walls.

  • Patent number: 8882018
    Abstract: A retainer for controlling the payout of wire from a wire container is described. The retainer has at least three segments. Each segment is connected to the adjacent segment so as to allow a relative movement of adjacent segments with respect to each other. The entirety of the segments form a contact surface adapted for contacting the wire contained in the wire container. Further, a wire container is described having a reception space for a wire coil, a wire coil arranged in the reception space, with the wire forming an annular end face of the wire coil from which the wire is withdrawn from the wire container, and a retainer for controlling the payout of wire from a wire container.

  • Patent number: 8127923
    Abstract: A container for accommodating a welding wire coil has a metal frame which defines an accommodation space for the welding wire coil. The metal frame has a bottom portion on which the welding wire coil is to be placed, and a side structure intended to laterally support the welding wire coil. The bottom portion of the metal frame is formed from four metal bars arranged so as to form a grid, and the side structure of the metal frame is formed by eight metal tubes, each of which is connected to one of the ends of the metal bars. The container further has a cardboard wall structure covering the outside of the side structure of the metal frame and having an octagonal shape in cross-section, and a cardboard floor structure covering the outside of the bottom portion of the metal frame. Furthermore, supporting feet are provided which are bolted to the metal frame and which clamp the cardboard floor structure to the bottom portion of the metal frame.
