AWE ARROW PRESS:HOT SPLINCING IN EIGHT SIMPLE. PRESS STANDARD VERSION. |

The fabric in process is about to finish and runs through the AWE ARROW splicing press.

As the fabric on the roll comes to an end, the operator activates the fabric lock command.
The pneumatic clamp (A) locks it while the accumulator positioned after it gradually cedes the fabric as it continues to move towards the fabric treatment line that will not have to be shut down.

Before continuing, the operator brings the end of the new fabric up to the roller coated with high “grip” black rubber (B). As this roll only rotates in the fabric feed direction it assists the operator as he pulls the head end of the new fabric by hand until it is stretched uniformly along the entire width. He then moves the rubberised roller up to the idle roll at the machine inlet to press the fabric and keep it stretched in a uniform manner.

At this point the operator overlaps the head of this fabric over the tail of the fabric in the machine by hand, then cuts both simultaneously and removes the scraps. The two fabrics to be spliced now have their edges perfectly aligned. At the cutting point, near the lower heated bar, there is a guide for the electric scissors. On request Z.P. ARROW can supply this special tool which has been designed for cutting very “difficult” fabrics.

The operator places the thermal adhesive tape on the edge of the fabric already in the machine, he rotates the idle roll (C) to advance the new fabric by 7/8 cm and places the head end of the fabric over the other end.

The tail end of the old fabric and the head end of the new fabric are now overlapping with the thermal adhesive tape between the two ends and the whole assembly is ready for the hot splice. The two fabrics are aligned and stretched equally, selvedges and centre.

The operator activates the closure of the hot splicing press and the splice is executed under the pressure of the heated bar (D). The time required varies from 40 seconds to 1 minute, depending on the thickness of the fabric.

Once the preset pressure time has elapsed, the heated bar is raised automatically. The operator releases the clamp (A) and the fabric once more feeds towards the accumulator in the direction of the finishing line. The splice has been executed without interrupting the production of the fabric treatment line.
