Continuously operating welding machine for film webs and bags - has jaws inside which gas is heated and then discharged at plasticising temp.

The material to be welded is conveyed into the welding zone by a conveyor belt system and then passed between 2 pairs of rollers which press the material together and cause it to coalesce. It is then conveyed to a cooling zone where cooling elements are supplied with cold air in the same manner as hot air was supplied for heating. The cooling elements allow the cooling air to impinge against the welding points to that the material finally issues completely welded and cooled. The material is simple and reliable in construction and is practically free from breakdowns. There is very little wear and tear, either mechanical or thermal, to which the equipment may be subjected.

Patching hole in thermoplastic fabric in paper-making machine - by cutting elliptical hole, spot-welding overlapping patch, and pressing while heating ultrasonically

Fabrics which contain thermoplastic threads are bonded together by overlapping them where they are softened by ultrasonic heating and are pressed together. The whole area of the overlap is heated at the same time, and the fabrics are pressed together at a pressure which brings them almost into one single plane. The process is particularly intended for use with thermoplastic polyester threads. To repair a hole in the sheet-forming fabric at the wet end of a paper machine the fabric is made taut as in service and is placed on a supporting plate. The hole is then punched out into an elliptical shape with sharp edges, and the plate is replaced with a steel plate. An ultra-sonic welder is centered in position over the hole.A patch is placed over the hole so as to overlap 1-3mm over the edges and the patch is spot welded at 2 or 3 points to fix it. An ultrasonic sonotrode is brought down to heat the overlapping area and to press the area with the patch. For this purpose the sonotrode is a ring ...
