Problems solved by technology

This produces a loss of quality in the subsequently formed combed sliver
Furthermore, the aforementioned air flow in the joint area is adversely affected by the cleaning elements (brush rollers; stripping rollers provided with pile, etc.) which rotate faster and faster due to the high clamping speed

Embodiment Construction

[0016] figure 1 shows a known clamp unit 1 , (shortly referred to as "clamp") mounted in a pivotable manner via crank arms 2 , 3 . In this case, the two crank arms 2 , 3 are in each case mounted pivotably laterally of the circular comb 4 on its circular comb shaft 5 . The circular comb 4 has a comb segment 7 on part of its circumference. The other end of the pivoting arm 2 is pivotally fastened to a shaft 10 on the nipper mount 8 . The rear pivot arm 3 (it is also possible to have two of them) is mounted in a rotationally fixed manner on a nipper shaft not shown here. The opposite free end of the pivot arm 3 is pivotally connected to the nipper mount 8 via a shaft 9 .

[0017] Usually a plurality of combing heads are arranged next to each other on the combing machine, wherein each combing head has a clamp 1 . However, the example shows and describes that the guard element according to the invention is fastened only on a single combing head.

[0018] The clamp 1 basically ...

Abstract

The invention relates to a combing machine, comprising a clamping assembly (1), which can be pivoted back and forth and which has a lower clamping plate (12) and an upper, movably supported clamping plate (14), a top comb (11), and a combing cylinder (4) rotatably supported inside a housing (50) below the clamping assembly (1), wherein the housing (50) is connected to a vacuum source (P) and has at least one opening (R2), which is connected to the space (R) between the clamping assembly (1) and a subsequent first roller pair (24), downstream of which a second roller pair (25) is arranged, and a rotatable cleaning element (34) is attached above the upper pressure rollers (24b, 25b) of the first and second roller pairs (24, 25). In order to eliminate disturbing effects on the soldering process by the air sucked out of the housing (50), it is proposed that a shielding element (30) is attached in the region between the clamping assembly (1) and the cleaning element (34), which shielding element extends over the length of the cleaning element, wherein the lower longitudinal edge (31) of the shielding element (30), which shielding element extends upward, is arranged at a distance (a) of between 0.1 mm and 7 mm from the circumferential surface (u1) of the pressure roller (24b) of the first roller pair (24).

Description

technical field [0001] The invention relates to a combing machine having a nipper unit pivotable to and fro and having a lower nipper and a movably mounted upper nipper, and a top comb and a rotatably mounted Cylinder combing in a housing below the nipper unit, wherein the housing is connected to a low voltage source and has at least one opening connected to the space between the nipper unit and the subsequent first pair of rollers in the first pair of rollers A second pair of rollers is arranged downstream of and a rotatable cleaning element is attached above the upper pressure roller and the first pair of rollers and the second pair of rollers. Background technique [0002] In known combers with a nipper unit pivotable to and fro ("nipper" for short), the fiber tufts protruding from the closed nipper are caught and combed out by the combing section of the circular comb. In doing so, the clamp is in the rear position. The tongs are then pivoted to a front dead center posi...
