Definitions

• the invention relates to a combing machine with rotating circular comb.
• the tuft to be combed out is held by the mouth of the tongs apparatus to the combing area of the circular comb.
• the round comb rotates under the tuft and grabs the needles of its comb strips.
• the replenished fiber tuft contains many tangled fibers, which are heavily loaded by the intervention of the needles. Accordingly, this is the risk of damage to shortening large.
• the object of the invention has been found to avoid this and to be able to use uniform needle bars. It solves this problem by reducing the engagement of the comb strips or needle bars in the initial area of Kämmfeldes to protect the fibers in the still tangled tuft thereby reduced that the needle bars are set lower or equipped with shorter needles.
• an embodiment of the invention is shown schematically. It shows the front view of a circular ridge with the envelope line over the tips of the combing needles.
• the circumferential in the arrow direction circular comb 1 is mounted on a shaft 2 and carries on a part of its circumference a Kämmfeld 3.
• a larger number of comb strips or needle bars 4 is arranged, which are occupied by needles 5.
• the needle bars are indicated only by their center lines. The manner of attachment of the needle bars on the circular comb is irrelevant to the present invention and therefore not shown and explained in detail. Saurer GmbH & Co. KG Z 0605 WO
• the circular comb 1 is a pliers apparatus 6 is delivered, in which a pair of rollers 7 a fiber wadding 8 a pliers 9/10 supplies. When the pliers are closed, the fiber tuft 11 projecting out of it is held up by the needles 5 of the needle bars 4 and combed out by the rotating circular comb.
• a fiber tuft 11 which has been pushed on when the tongs 9/10 are open, contains many fibers that are still tangled and anchored in it.
• Five needle bars in an initial region 12 of the Kämmfeldes 3 set back so far that the H envelope over the tips of the needles 5 of these needle bars to the Dimension h lowers approximately to the circumference of the circular comb 1. This ensures that the engagement of these needle bars is gentle and the confused fibers are given the opportunity to insert themselves into the gaps between the needles without running the risk of being torn off.
• the set back is achieved in that the support surface 13 of the circular comb 1, on which the needle bars 4 sit, is lowered in the initial region 12 of the Kämmfeldes 3 according to a measure h.
• Needle bars in the initial region 12 of Kämmfeldes 3 and needle bars lesser height can be used, which then stand on the same amount remaining support surface 13 of the circular comb.
• needle bars 4 can be equipped with shorter needles with the same height of their web 14 or equal long needles 5 are soldered to webs of lesser height.
