Abstract
A beaming device for fabrics and in particular for very elastic fabrics is described which comprises a first pair of rollers (3,5) for entraining the fabric from a textile machine, a second pair of rollers consisting of a winding roller 13 around which the said fabric is to be rolled in rolls and driving roller 11. The second pair of rollers turn at a lower speed than the first pair. The winding roller is caused to rotate by the driving roller 11 which in turn is rotated by the entraining roller 3 of the first pair of rollers by means of a transmission comprising a speed controller. The driving roller 11 is arranged between the said first pair of rollers and the beaming roller 23. The fabric to be wound loses any deformation caused by the first pair of rollers when it goes through the part 2' between the two pairs of rollers.
Claims9
A beaming device for winding fabrics into rolls and in particular for winding very elastic fabrics, comprising a first pair of rollers for entraining the fabric from a source thereof:
- a winding roller around which the said fabric is to be rolled in a roll, a device in which the winding roller is made to rotate by a driving roller in turn rotated by an entraining roller of the first pair of rollers through a transmission comprising a speed controller.
A beaming apparatus for winding a web of material into a roll thereof, which comprises a base means;
- a pair of rollers supported by said base means for rotation relative thereto, a first roller of said pair of rollers being rotatably driven and a second roller of said pair of rollers being a freely rotatable idler roller, said first and second rollers being disposed to grip between them an incoming web of material and to draw said web into the apparatus at a given speed;
- a third roller supported by said base means for rotation relative thereto and rotatably driven, a fourth roller supported by said base means for rotation relative thereto, said fourth roller being a freely rotatable idler roller and disposed to support the web roll being wound from said incoming web;
- said third roller being disposed to receive said incoming web from said first and second rollers and to frictionally engage the web roll on said fourth roller to rotatably drive same to wind the web;
- and a transmission coupled to said first roller and to said third roller to drive said third roller at a predetermined reduced speed in relation to the speed of said first roller to relieve distortion in the web as wound into said web roll.
