Embodiment Construction

[0017] Figure 1 is a schematic diagram showing a revolving flat card, for example a Ritter C60 card, with a working width of more than 1.3 m, in particular 1.5 m. The principle of the invention can be applied to working widths of up to 2 m, and can also be used in cards with conventional working widths of about 1 m. The working width of the card is effectively determined by the axial length of the clothing surface on the cylinder 1 .

[0018] In operation, the tow is conveyed by pneumatic conveying ducts through the various opening and blowroom stages (not shown) before being formed into a batt in the infeed chute 16 of the carding machine. The chute 16 in FIG. 1 is designed as a so-called "cleaner chute" with a cleaning module 15 located between the upper part of the chute and the lower part of the chute. However, this is not essential to the invention, and instead of the cleaner chute it is also possible to provide a conventional feed chute. The chute then conveys the fibe...

Abstract

Sawtooth wire for production of a sawtooth solid steel fitting for the processing of textile fibres, in particular, for the production of a sawtooth solid steel fitting for the doffer of a carding machine. The breast angle a1 is between 32 DEG and 45 DEG which is novel.

Description

technical field [0001] The invention relates to a sawtooth metal wire for manufacturing a sawtooth all-steel card clothing for processing textile fibers, in particular for making a sawtooth all-steel card clothing for a doffer of a carding machine. The metal wire has a plurality of teeth arranged continuously along the longitudinal direction of the wire, each tooth has a tooth end face extending from the tooth root toward the tooth tip, and a tooth back extending from the tooth tip toward the next tooth root. Background technique [0002] to sort out [0003] Various cleaning and / or carding areas are provided on the carding machine. The fiber feed is supplied to the carding machine in the form of batt. The batt is initially pre-cleaned by licker-in rollers (formerly also called licker-in rollers). The licker-in consists of one to three rollers with a relatively coarse card clothing which further opens up the batts before conveying them to the cylinder. The fibers are dof...
