Modern lace production requires high-tech solutions at every stage of the manufacturing process and that is why Karl Mayer is constantly improving and revamping its range of lace raschel machines and coming up with new innovations in warp preparation at the same time. One of the latest innovations to come from the renowned manufacturer of warp preparation equipment is the PBW 130/2 pattern beam warping machine.

Karl Mayer claims that this new machine offers optimum productivity, process reliability, ergonomic features and top-quality winding. The advantages claimed have been achieved by extensively revamping and optimising the machine design.

Higher productivity through innovation

The patented friction drive at the circumference of the pattern beam is equipped with just one roller, operates slowly by means of a frequency-controlled three-phase current motor, and has been combined with a newly developed electromechanical traversing drive. The synchronised operation of the two drives permits yarn laying to be carried out so as to achieve precise cross-winding when building up the package. The high reverse acceleration and controlled stroke shifting at the reversing points also enable a perfect edge to be produced, without any raised edges on the package. Pattern beams featuring bi-conical precision winding and a stable construction are produced.

Further features of the high-quality beams include active calculation of the winding conditions and optimum guiding of the yarn using the principle of constant yarn spacing to the run-in point. According to Karl Mayer, the new PBW 130/2 operates quietly and at a higher warping speed than its predecessor, and is equipped with a modern control system. The human/machine Interface (HMI), which is operated via a 3.5" touch screen, enables all the relevant warping parameters to be input easily, and permits information relating to the production process to be called-up .

Applications

The PBW 130/2 is particularly suitable for the simultaneous warping of two pattern beams having different yarn spacing values. The beam length is 330 cm or 130", ‘System Mayer’, and the maximum diameter is 140 mm. The associated creel is a standard creel with 128 take-off points arranged in eight levels, each having 16 packages. Karl Mayer says that the infinitely variable warping speed of 0 to 400 m/min makes the new, efficient PBW 130/2 to an indispensable piece of equipment for producing short runs and test fabrics, as well as for large-scale production.
