Abstract
The device of the invention enables a fiber web at the outlet from a carder to be removed and conveyed at high speed without significant change to the structure of the web, and in particular without stretching the web. The device comprises a takeoff cylinder which is adjacent to the last working cylinder of the carder, suction means, and a conveyor belt. The belt of the conveyor is permeable to air, and at least level with the takeoff cylinder it possesses at least one rectilinear web-receiving portion that passes close to the takeoff cylinder with a linear speed that is substantially equal to the peripheral speed of the takeoff cylinder, travelling in a direction that is orthogonal to the axis of rotation of the takeoff cylinder, and interposed between the suction means and the takeoff cylinder. The suction means establish a suction zone between the takeoff cylinder and the rectilinear portion of the conveyor belt, substantially in the vicinity of the line where they are almost tangential.
