Problems solved by technology

[0011] In particular, it is understood that the denser fiber flow to the opener causes the output fiber bundles to still be contaminated with impurities and heavily entangled, thus not being able to achieve satisfactorily good results in downstream further processing

Embodiment Construction

[0023] Referring to the accompanying drawings, reference numeral 1 each denotes an assembly for fiber tow processing, which constitutes a part of a fiber processing line.

[0024] The assembly comprises a supply line 2 for conveying the fibers to be processed, eg from a draw frame.

[0025] The assembly comprises a supply device 4 suitable for separating the dust laden air from the fibres. The fibers F to be processed are conveyed towards the device 4 , for example by suction applied by a fan housed in said device 4 . An exhaust pipe 6 protrudes from the device 4 to discharge the inhaled dust-laden air A.

[0026] According to an embodiment variant, the fan is housed outside the device 4 .

[0027] Furthermore, the assembly 1 comprises, downstream of the supply device 4 , an axial flow opener 8 comprising an inlet pipe 10 connecting it to said supply device 4 .

[0028] The inlet pipe 10 generally extends along an entry line X which is located approximately at a vertical po...

Abstract

An axial opener (8) for fibers in tufts comprising an input pipe (10), opener rollers (16,22) and a separation 5wall (42) upline of the cleaner rollers, to separate the compartments where the rollers are lodged and channel the fibers to be processed in part towards the first compartment and in part towards the second compartment of the opener.

Description

technical field [0001] The invention relates to an axial flow opener for fiber bundles. Background technique [0002] It is known that in order to obtain a textile yarn from a fiber, the fiber must pass through a number of operations in order to remove impurities and dirt therefrom, to align and straighten the fiber. These processes produce slivers, which are then processed, for example on spinning machines, to obtain yarns. [0003] Different processes are carried out by different machines, because these operations need to be repeated many times with increasing intensity in order to obtain the desired result. [0004] In particular, eg for processing the fibers, bundles of fibers are stretched by a draw frame so that fiber bundles are obtained which are transported by an air flow. [0005] The fiber bundle is then processed in the machine to remove impurities such as stones or non-ferrous substances mixed in the fiber bundle before it enters the axial flow opener; in the ...
