A coiler plate (19 fig. 1) for a sliver-coiling device, comprises a sliver channel 20 having an inlet 20a and an outlet 20b for sliver and having a rotary means such as a rotary plate 21 or a cover 22, the rotary plate 21 or cover 22 having a through-opening and the sliver channel 20 is joined to the cover 22 or rotary plate 21 by means of a joining method for metal materials. The joining method may be laser beam welding or soldering. The cover 22 may be provided on the underside of the rotary plate 21. The cover 22 and sliver channel 20 may be made from wear resistant, low friction, metal material such as special steel. The rotary plate 21 may be cast aluminium. The through-opening may be oval or kidney shaped and may be formed by laser beam cutting after the sliver channel 20 is joined to the rotary means. The sliver-coiling device may be used on a spinning room preparation machine, especially a carding machine, draw frame, combing machine or the like. |
