Embodiment Construction

[0026] figure 1 A schematic diagram of a carding machine with a cylinder 1 , feed roll 2 , a licker-in roll 3 and cleaning roll 4 is shown. exist figure 1 The directions of circumferential rotation of the middle rollers are respectively indicated by arrows.

[0027] The card clothings described below are in each case rollers or cylinders which actively take up fibers from rollers arranged in front of them in the working direction. For example in figure 1 In the illustration shown these are the licker-in roller 3 , the cleaning roller 4 and in particular the cylinder 1 .

[0028] Now figure 2 A partial view of a toothed strip of all-steel card clothing, which is used, for example, in figure 1 rollers shown in . Here it is a sawtooth rack with an overall height of 2 mm and a pitch of 1.7 mm measured from one prong 5 to the next prong 5' ( ). The rake angle α of the tooth front face 6 measured relative to the vertical line is 40° in the exemplary embodiment shown here. ...

Abstract

The invention relates to an all-steel card clothing for rollers and / or drums of carders or carding machines. Carders or carding machines comprise rollers which are configured in order to actively receive raw fibre materials. Said card clothings have a relatively large breast angle which has a negative effect on the stability of the card clothings. According to the invention, the teeth have a head angle of > 85 DEG in order to solve this problem. The length of the head surface extending from the tip of the tooth to the rear of the tooth corresponds to at least 1 / 4 of the length of the tooth pitch.

Description

technical field [0001] The invention relates to an all-steel card clothing for the rollers and / or cylinders of clearing machines, carding or carding machines, which rollers or cylinders have a higher peripheral speed than the respective preceding rollers in the direction of fiber advancement, The all-steel card clothing has teeth with a positive rake angle ≥ 0°. Background technique [0002] Rollers here are, for example, licker-in rolls on carding or carding machines, cleaning or transfer rolls, and cylinders on carding or carding machines. These rollers or cylinders actively receive the fiber material with the leading edges of the leading edges of the corresponding all-steel teeth. [0003] The problem with such all-steel card clothings is that a positive rake angle is required to ensure good fiber reception. However, this tends to result in a tapering of the tooth tips, which makes such card clothings more susceptible to damage during assembly and fine grinding. In add...
