Embodiment Construction

[0020] according to figure 1 and 2 The illustrated fiber bundle device 1 for compacting a fiber strand 2 is a component of a spinning machine, in particular a ring spinning machine. Each spinning position of this spinning machine has a only partly shown drafting mechanism 3, with respect to which mechanism only a delivery roller pair 4 and a small belt pair 5, 6 located at the front are shown.

[0021] The output roller pair 4 comprises a bottom roller 7 designed as a bottom roller cylinder driven continuously in the longitudinal direction of the machine, which is equipped with a pressure roller 8 at each spinning position. The bottom roller 7 and the pressure roller 8 mutually form an output nip line 9 which ends in the drafting area of ​​the drafting mechanism 3 .

[0022] A fiber strip or alternatively a roving 10 is delivered to the drafting mechanism 3 in the transport direction A and is drawn in a known manner to the desired fineness in the drafting mechanism 3.

Abstract

The invention relates to a reinforced embedded component of suction channel in fiber beam device of spinner. The reinforced embedded component is equipped with a fixing device to fix it in the suction channel. The fixing device has the same material with the reinforced embedded component and is integrated with the reinforced embedded component. The reinforced embedded component comprises fixing devices for shape cooperating joint and transfer joint. The invention also relates to a suction channel for fiber beam device of spinner. The suction channel has a tube base, on the outline of the baseincluding a first sliding surface for ventilating conveyer belt, on the sliding surface having a suction slot winded on the direction of the circle of the base. The suction channel has a vacancy withnotch shape for reinforcing embedded component on the end of the suction slot. The reinforced embedded component has a second sliding surface for extending the first sliding surface. Cooperating withthe invented reinforced component, the notch vacancy has a free notch with undercut.

Description

technical field [0001] The invention relates to a reinforcement insert for a suction channel of a fiber bundle device in a spinning machine, wherein fastening means are provided for the reinforcement insert for fastening in the suction channel. [0002] The invention also relates to a suction channel for a fiber bundling device on a spinning machine, which has a tubular base body, the outer contour of which contains a first sliding surface for the air-permeable conveyor belt, the sliding surface has a substantially arranged on the base body suction groove in the circumferential direction, the suction channel also has a substantially groove-shaped recess at the end of the suction groove for a reinforcing insert with a second sliding surface extending the first sliding surface . Background technique [0003] Pneumatic compaction of a fiber strand leaving the drafting device is characterized in that the fiber strand is carried out in the untwisted state with fibers substantial...
