Warp tying is an essential process in every weaving mill. Until the beginning of the last century, this process was conducted manually. The first warp tying machines appeared in the 1930s. Mechanized warp tying had revolutionized the industry worldwide. At that time, the Swiss company Uster offered the KLEINUSTER/USTERMATIC for automatic warp tying. As part of its global marketing strategy, Stäubli acquired this product line and developed it further, which resulted in the TOPMATIC, one of the world’s leading tying machines. The design successfully integrates the workflow requirements of the mill with a number of various technical weaving solutions developed by Stäubli. Continuing development made this machine a highly reliable and important component in many mills. In line with its credo – every development must bring customer benefits – Stäubli constantly pursues its commitment to R&D. Its new TIEPRO warp-tying machine incorporates very special and unique features that make it as inevitable as the tying process itself.

Easy and rapid start-up

Any type of tying machine to be used in a mill must first be placed on the warp-tying frame at the weaving machine. An operator has to dock the machine by hand. Equipped with robotics, TIEPRO docks itself to the old and the new warp sheets. Afterwards, the operator can simply confirm start-up by pushing the start button – and automatic warp tying begins. Thus, TIEPRO leaves staff more time to oversee the weaving hall or handle other tasks.

Easy handling

Before tying, and during the warp stretching on the tying frame, typically, the yarns of new and old warp sheets don’t align precisely. This fact can require time-consuming effort during the tying process. But not with TIEPRO. It easily handles misalignments of up to 10 mm, ensuring precise and quick preparation.

TIEPRO incorporates a revolutionary form of automatic Double End Detection (DED) as a standard feature. Stäubli DED detects double ends automatically before the warp yarn is cut.

This outstanding feature is unique. Another standard feature is the Auto Reverse function, which works in conjunction with DED during the yarn separation process. Double ends caused e.g. by sticky yarns are detected by the sensor, immediately extracted, and separated. This process is done automatically within milliseconds and is virtually impossible to follow visually. It requires no operator intervention. Once done, the yarn separation process automatically restarts.
