A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

The invention relates to an automated sewing system comprising I) a sewing head or ultrasonic welding head configured a) for connecting two or more layers of fabrics, or b) for making a pattern on one or more layers of fabric; and II) a conveyor belt unit comprising i) a conveyor belt adapted for supporting one or more layers of fabric, and ii) a motor unit adapted for moving said conveyor belt; wherein said conveyor belt further comprises c) a mechanism adapted for forming a cavity in said conveyor belt, said cavity being formed below said sewing head.

The purpose of the present invention is to produce a three-dimensional formed body by connecting only cloth pieces without using a fixing device such as sewing. The peripheral edges of the central part of this bottom part cloth piece has first peripheral edge parts provided with first notches having the same shape as a basic cloth piece, and second peripheral edge parts provided with second notches. The first notches of the bottom part cloth piece are engaged with second notches of the basic cloth piece by matching each notch with a corresponding notch. The second notches of the bottom part cloth piece are engaged with first notches of the basic cloth piece by matching each notch with a corresponding notch.

A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.

The invention relates to a device and a method for connecting finite webs of material for the energy cell producing industry, wherein the device comprises a holding device adapted to hold the new web of material by means of negative pressure in the second guide section, as well as a backing element and a cutting element, downstream in the conveying direction of the holding device. The backing element and the cutting element are adapted to cut the stationary new web of material to produce a new leading end of the new web of material. The device also comprises an applicator for applying an adhesive strip to the new leading end of the new web of material and a ram and a cutting device, wherein the cutting device is adapted to cut the stationary running-out web of material to produce a new trailing end of the running-out web of material. The ram is adapted to press the trailing web end of the running-out web of material onto the adhesive strip and against the applicator in order to connect the new leading end of the new web of material to the new trailing end of the running-out web of material.
