Weft Insertion System - AXIAL

Weft insertion principle

The weft threads are hung into the hook elements of transport chains as a function of system by means of weft inserter or a feeding unit and fed to the knitting area. The weft threads are cut-off depending on the weft insertion principle either after fixation by knitting threads or directly upon insertion into the hook elements of transport chains.

Endless weft insertion

The weft carriage moves in three axes i.e. in x-axis (angle-dependent carriage movement lengthwise to weft carriage support), y-axis (racking movement of hook chain), and z-axis (press-in movement).

 

Pin-hook system 

The weft threads are laid endless around the hooks of transport chain. When overtravelling the pins, the weft layer is positioned in its width.
Use of hooks ensures high yarn counts and extreme tensile forces upon weft insertion. The vertical pins maintain high uniformity of weft layers.


Pin-pin system 

The weft threads are pressed endless into the pins of transport chains. When overtravelling the pins, the weft layer is positioned in its width. Thanks to the use of horizontal pins, utmost flexibility of useful insertion curve geometries is possible.

Insertion of cut weft threads

 

Malitronic MULTIAXIAL Cut & Lay

 

The movements of axes have been segregated, the weft carriage moves both in x-axis (angle-dependent carriage movement lengthwise to the weft carriage support) and z-axis (press-in movement). A clamping and cutting unit cuts the weft layers and sustains movement in z-axis (press-in movement). The weft layers are inserted into the hook elements of transport chains in line with the spread width (y-axis - racking movement of hook chain). The parallel movement and cutting-off of weft layers ensures deflection-free processing of broad tapes (e.g. torsion-free carbon filament yarn).
