Bias Binding Tape

Bias tapes, as they have been used in textile processing for centuries, offer two main advantages due to the diagonal course of warp and weft: Firstly, elasticities can be produced in standard fabrics and thus three-dimensional structures can be better reproduced. Secondly, fraying of the cut edges is reduced. The patented invention of the seamless bias tape process by company founder Gerhard Topp at the end of the 1940s revolutionised the previously predominantly manual production of bias tapes beyond the borders of Germany and paved the way for the success story of the Topp Textil Group.

Although today the product range at Topp Textil is dominated by a multitude of other production technologies for a wide variety of textile flat goods and narrow textiles, the textile cut tape continues to be an important part of the company. Thanks to modern machinery based on different cutting technologies such as roll slitting and unwinding processes, Topp Textil is able to cut any type of woven, knitted, knitted or non-woven fabric in straight and diagonal versions. The basis for industrial slanted belt production is always the textile tube, which is produced in woven, knitted, sewn, glued or welded form at Topp. The minimum width for industrial hose production is 90 cm of fabric, which corresponds to a hose width of approx. 43 cm. For a cut textile band or edging band, the minimum width is usually 5 mm, whereby a cutting accuracy of +/- 1 mm can be guaranteed as standard. Depending on the desired tape elasticity, the company produces straight tapes, semi-diagonal tapes at an angle between 8°-12°, or diagonal tapes at an angle of 45°.

To prevent fraying of synthetic textile fabrics, the textile tape can be hot-cut with hot knives or ultrasound. Topp Textil offers hot-cut tapes as standard from a width of 10 mm. Other forms of processing straight tapes and bias tapes such as printing, punching, perforating, sewing, coating and gluing as well as various folding processes (e.g. centre folded, double folded, folded with gap) then follow.
