Embodiment Construction

[0009] Such as Figure 1a and 1b Drum 1 feeds fibers into doffer 2 as shown in . The hollow plate 3 introduces the fibers into the middle region 4 . The suction device 5 leads into the area of ​​the wedge member. In order to avoid collapse or deformation of the suction gap, the suction opening is interrupted and divided into a plurality of suction openings 6 .

[0010] Such as Figure 2a and 2b As shown in , the suction opening or suction gap 6 is not interrupted over the working width. A support surface 7 is mounted behind this opening. The support surface 7 has a further opening 8 through which the sucked air passes. The support surface 7 supports a load-bearing surface 9 which better guides the fibers in the wedge-shaped member. The opening 8 has, with respect to its maximum extension x, an approximate dimension to the working width y of the machine, eg a carding or opening device. Preferably, the opening 8 extends with respect to its maximum extension over 30% of t...

Abstract

The invention relates to a suction device which is situated between two rollers at a carding device or a carding device, wherein a support plate for the suction opening and the fiber guiding element is integrated in the suction device.

Description

technical field [0001] The invention relates to a suction device, in particular to a suction device for the suction of fibers at the transition region between a drum with an add-on and an adjacent drum with an add-on during a carding or opening process device. Background technique [0002] An important function of the carding and opening devices is the transition of the fibers from the final drum to the doffer. This is easy for longer fibers, whereas short fibers require better guidance in wedge-shaped elements (Zwickels) between the rollers. [0003] However, due to limitations in mechanical engineering, guidance is only permitted via hollow plates, which terminate a few millimeters in front of the wedge-shaped component. The resulting openings allow dust and fiber to escape at high speeds and high fiber loads. [0004] It is therefore advantageous to introduce a suction device close to the wedge-shaped component. For large working widths of several meters long, large g...
