Embodiment Construction

[0022] In the suction zone for feeding the fibres into the carding machine, not shown, a feeding disc 1 cooperating with a feeding roller 2 is provided. Between the feeding pan 1 and the feeding roll 2, the fiber fleece bundles are conveyed in the form of fleece to an opening roll 3, also called a licker-in or licker-in roll. The opening roll 3 separates the fibers introduced into single fiber strands. The impurities contained in the pile fabric are fed to the feed roll 2 and the opening roll 3 together with the fibers. Due to the centrifugal force acting on the impurities, these impurities are centrifugally acted on the opening roll 3 and leave the opening roll 3, or at least the good fibers which are lighter or more inert due to their mass are further removed by the opening roll 3 rise. It is also beneficial to separate the dirt particles from the good fibers by means of a separating knife 4 which defines the dirt separating holes 5 in the casing 6 of the opening roll.

Abstract

A textile carding machine has a feed roller advancing a non-woven fibres to a separation roller. The foreign body separation hole is disposed in the discharge roller zone to separate the fiber and the foreign body. The outlet has a discharge passage with a discharge zone and an air flow zone. The foreign body outlet zone is disposed in the zone of foreign body separation hole and separated from the air flow zone. A curtain is arranged in the foreign body separation zone and air flow zone for the purpose of preventing against interference of the discharge of the foreign body inside the air flow.

Description

technical field [0001] The invention relates to a carding machine with a feed roll, by means of which fibres can be transported in the form of fibre laps to an opening roll, whereby dirt separation holes are provided in the region of the opening roll for removing dirt Fibers are separated from impurities at the separation holes, channels are provided at the dirt separation holes to guide the impurities to leave, and the channels form a dirt removal area and an air intake area. Background technique [0002] US-P3955244 discloses a carding machine with a feeding roll and an opening roll formed with a plurality of dirt separation holes. The dirt separation zone is basically divided into two parts. Large holes are provided in the first part of the feed roller for separating the coarser dirt, followed by an area in which a plurality of rods are provided at a distance from each other. The gaps between the rods are used in particular to separate fine dirt particles. A cavity is ...
