Also suitable for smooth yarns

The PBW 130"/2 is suitable for processing a wide range of different yarns. If very smooth yarns have to be processed, biconical packages with an angle of up to 60° guarantee a slip-free build. With this tapering shape, the edges of the yarn layers form a bevel, which prevents the upper layers from falling down. The more acute the angle selected, the narrower is the package and the greater is the loss of volume as well. A loss in output is unavoidable with biconical warping.

User friendly and accessible technology

The PBW 130"/2 scores points by having a well-thought-out, easy-to-input logistics system operated via a touchscreen monitor. The user interface is available in German, English and Chinese. To make things easier for the operators, especially when inputting data relating to the warping jobs, menu navigation is restricted to one side of the screen. Here, the operator can select the four parameters relevant to the job.

The machine’s computer automatically calculates the remaining parameters in the background, such as the package ratio, return path of the traverse motion and winding ratio, and adjusts them to the best possible ratios.

Since the PBW 130"/2 can simultaneously produce two pattern beams completely independently of each other on two levels, the screen is divided into two halves. The processes involved in producing the two beams run completely autonomously. Only in the event of a yarn breakage is the operation stopped at both the upper and lower levels for safety reasons.

If two jobs that are the same follow each other, only the beams have to be changed. After one batch has been worked, the machine detects the residual warping length as zero, stops the process, and organises the restart itself. The reset key only needs to be pressed if a warping job is stopped.

The PBW 130"/2 will be showing these features and more at ITMA ASIA + CITME from 16 to 20 June on KARL MAYER’s stand in hall E 3, stand D 01.
