Embodiment Construction

[0030] exist figure 1 A system for making synthetic staple fibers from tow is schematically shown in . The system has a processing device 3 to receive the tow for processing and splitting. The processing device 3 is also known in the technical field as a so-called fiber production line for the continuous production of staple fibers from tows. exist figure 1 The treatment device 3 shown in can thus be combined with the melt-spinning device 1 or optionally with the can station 2 . The treatment device 3 is thus suitable for both a one-step process and a two-step process for producing short fibers.

[0031] exist figure 1 In , the melt-spinning device 1 and the can station 2 are shown symbolically and will not be further explained here.

[0032] The processing device 3 comprises in this embodiment a plurality of stretching devices 4 and 5, a sizing device 12, a distance shifting device 14, a crimping device 15, a belt dryer 16, a draw adjustment device 17 and a Cutting devi...

Abstract

The invention relates to a method and an apparatus for the quality control of a multiplicity of melt-spun fibre strands of a fibre tow in a staple fibre process. For this purpose, fibre strands of the fibre tow are guided one beside the other, and parallel to one another, in band form and are jointly crimped and cut to form staple fibres. Prior to the cutting operation, at least one surface property of the fibre tow is detected and analyzed. In order to uncover possible abnormalities within the fibre tow, the invention provides for a surface temperature of the fibre strands of the fibre tow to be sensed over the surface area, or linearly in a direction transverse to the fibre tow, and analyzed.

Description

technical field [0001] The invention relates to a method according to the preamble of claim 1 for quality monitoring of a mass of melt-spun fiber slivers of tow and a method according to the preamble of claim 8 for Equipment for quality monitoring of mass melt-spun fiber slivers of tow during the staple / staple fiber process. Background technique [0002] A method of this type and an apparatus of this type for quality monitoring of a plurality of melt-spun fiber slivers of tow are known from document WO 2007 / 073784 A1. [0003] It is common in the production of staple fibers that a plurality of fiber slivers are produced during the melt-spinning process. In a one-step process / single-stage process the fiber slivers are drawn, texturized and cut into fibers directly after melt spinning. In a two-step process / two-stage process, after melt spinning, the fiber slivers are deposited in cans in order to be subsequently drawn, texturized and cut as tows in the fiber production line...
