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. The operator cuts the end part of the fabric at 90º. A perforated suction table holds the fabric at the point where the cut guide slot is located..

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 roll at the machine inlet to press the fabric and keep it stretched in a uniform manner.

The operator places by hand the end of this fabric on the suction bar of the mechanism that will overlap the two fabrics. After placing the thermal adhesive tape on it as well, he cuts off the excess edge with the special ARROW electric scissors along the length of the guide.
The cut will be at 90º and the edge to be overlapped will remain stretched as it is held in position by the action of the suction device.

The suction bar rotates and automatically overlaps the end of the fabric to be spliced with the thermal adhesive tape on the tail end of the fabric already in the machine. The suction on the press table remains but on the mechanism is shuts off in order to release the fabric.

The suction bar returns to its standby position. This mechanism makes overlapping the two fabrics easier, faster and more precise, a feature that is particularly appreciated when the width of the fabric exceeds two metres.

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.

Just as in the standard press, the operator activates the closure of the hot splice press and the splicing is executed under the pressure of the heated bar (C). The time required varies from 40 seconds to 1 minute, depending on the thickness of the fabric. As soon as the press reaches operating pressure the suction on the press table cuts out.

Just as in the standard press, once the preset pressure time has elapsed, the heated bar is raised automatically. The operator releases the clamping device (A) and the fabric once more runs towards the accumulator in the direction of the finishing line. The splice has been executed without interrupting
the production of the fabric
treatment line.
