Problems solved by technology

[0011] In particular, it has been determined how the high flow of fibers reaching the opener produces at the exit a bundle of fibers that is still contaminated with impurities and is very entangled, which is not satisfactory for good efficiency of other downstream processing operations

Embodiment Construction

[0023] Referring to the drawings, reference numeral 1 generally designates an apparatus with an axial flow opener for processing bundled fibres, which apparatus forms part of a fiber processing line.

[0024] According to one embodiment, the device comprises a single input duct 2 with two or more branches 2', 2" to convey the fibers to be processed, e.g. from a pick-up unit ( Figure 4 ).

[0025] According to another embodiment, the device comprises suitably separated input ducts 2a, 2b for the transport of the fibers to be processed ( Figure 5 ).

[0026] It should be noted that in Figure 4 and Figure 5 In , the ducts are shown vertically for illustrative purposes; whereas in reality, it is apparent that the ducts extend along a horizontal axis.

[0027] The plant comprises feeding means 4 for feeding the fibers to downstream machines, in particular also adapted for separating the dust-laden air from the fibers.

[0028] For example, the fibers to be processed are co...

Abstract

A feeder device (4) of a machine on a processing line preparing fibre for carding, comprising a cleaner roller (4a) and a feeder roller (4b), downline of the cleaner roller, and separation devices for separating or keeping separated the incoming flow of fibre into two or more flows of fibre to feed to the machine downline.

Description

technical field [0001] The invention relates to a feed device for a machine on a processing line preparing fibers for carding. For example, the invention relates to feed devices for axial flow openers. Background technique [0002] It is well known that in order to obtain textile yarns from fibers, many processing operations must be carried out on the fibers to remove impurities and dust from the fibers, to align the fibers and to draw them. A fiber sliver is obtained by such a processing operation and subsequently processed, for example on a spinning frame, to obtain a yarn. [0003] The processing operations are carried out on different machines, because in order to obtain an excellent product it is best to carry out these operations in several distinct and progressively more intense stages. [0004] Specifically, in the exemplary fiber processing line, bundles of fibers are picked up by a pick-up device to obtain fiber bundles conveyed by airflow. [0005] The bundled ...
