Embodiment Construction

[0009] like Figure 1a and 1b Drum 1 feeds fibers into doffer 2 as shown. The hollow sheet 3 introduces fibers into the intermediate region 4 . The suction device 5 leads to the region of the wedge-shaped 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] like Figure 2a and 2b As shown, the suction opening or suction gap 6 has no interruptions in the working width. A support surface 7 is mounted behind this opening. The support surface 7 has a further opening 8 through which the suctioned air passes. The support surface 7 supports the bearing surface 9 which better guides the fibers in the wedge-shaped member. The opening 8 has, with respect to its maximum extension dimension x, a size that approximates the working width y of the machine (eg carding device or opening device). Preferably, the opening 8 extends over 30% of the working width y of the machin...

Abstract

The invention relates to a suction device which is located between two cylinders on a carding or opening device, wherein a support plate for a suction opening and a fiber guide element is integrated in the suction device.

Description

technical field [0001] The invention relates to a suction device, in particular a suction device for the suction of fibers in the transition region of one drum with attachments and an adjacent drum with attachments during carding or carding processes device. Background technique [0002] The important function of the carding device (Karden) and the opening device (Krempeln) is to transfer the fibers from the final drum (Tambour) to the doffer (Doffer). This is easy for longer fibers, while short fibers require better guidance in the wedge-shaped elements (Zwickel) between the drums. [0003] However, due to mechanical limitations, the guidance is only permitted via hollow core plates, which end a few millimeters in front of the wedge-shaped element. The resulting openings allow dust and fibers to escape at high speeds and high fiber loads. [0004] It is therefore advantageous to introduce the suction device close to the wedge-shaped member. Large gaps are unstable for l...
