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.
Claims21
A retainer for exerting a braking effect on wire provided as a spool in a container, having a plate-like elastic element with a contact surface adapted for resting on said wire, an outer circumference adapted for being guided in said container, and an inner circumference adapted for allowing said wire to pass through, said plate-like elastic element having an elasticity such that one of said inner and outer circumferences sags down, under the proper weight of said retainer, by a distance of at least 10 mm when said retainer is supported at the other of said inner and outer circumference.
A retainer for exerting a braking effect on wire provided as a spool in a container, having a plate-like elastic element with a contact surface adapted for resting on said wire, an outer circumference adapted for being guided in said container, and an inner circumference adapted for allowing said wire to pass through, said plate-like elastic element having an elasticity such that when said retainer is supported along a diameter, opposite sides of said retainer sag down, under the proper weight of said retainer, by a distance which is more than 5% of said diameter of said retainer.
A welding wire container having a bottom, circumferential walls extending upwardly from said bottom, a welding wire coil formed from a plurality of windings of welding wire, and a retainer which rests on an upper surface of said coil, said retainer having a plate-like elastic element with a contact surface adapted for resting on said wire, an outer circumference adapted for being guided in said container, and an inner circumference adapted for allowing said wire to pass through, said plate-like elastic element having an elasticity E which is in a range of 0.05 to 0.4, with the elasticity E being determined by the following formula:
- E

- B
- with:
- the 0.2% yield limit of the welding wire in N/mm2;
- the specific weight of the welding wire in g/cm3;
- B being the widths of the retainer from said inner to said outer circumference in mm.
