Knotmaster: The High Performance Tying Machine
In order to establish optimal communication in the Chinese market, the Groz-Beckert WeChat Account went online in 2017. Since then, the needle manufacturer has been providing weekly news on the company, its products and services, as well as the latest topics relating to all aspects of the Chinese textile market. As usual on WeChat, the content is published in Chinese – the Groz-Beckert Account also includes links to content in English.
This year, a new acrylic exhibit of a sock machine rounds off the glass insights into the different knitting technologies. The exhibit demonstrates a wide range of Groz-Beckert products in different gauges – with needles and system parts for ten different models from the fields of socks and seamless hosiery.
Whether cleaning, drawing-in, tying or weaving: As a system provider, Groz-Beckert offered a unique product variety with its Weaving division. Visitors could experience some of these products at ITMA Asia. The high-performance tying machine KnotMaster presented in the field of weaving preparation. It is characterized by a wide variety of functions, ranging from single and double knots and short knot ends, through to four knotting types and thread breakage monitoring.
VISITORS COULD EXPERIENCE WEAVINGLOOM
Heald frames and healds, as well as warp stop motions, drop wires and the PosiLeno® leno system been available for customers to experience in action in the WeavingLoom, a replica weaving machine made from acrylic glass. Four fabric strips also presented, highlighting the different applications, from leno to jacquard fabric.
As a development partner, Groz-Beckert has expanded its range for application advice with is own staple fiber needle punch line in the field of Felting (nonwovens) in the Textile and Development Center (TDC) in Albstadt, Germany. The division also presented its patented GEBECON® Felting Needle, which offers improved surface quality and optimal bending resistance. The EcoStar® Felting Needle is a real highlight for all applications with the highest demands for surface quality. It is characterized by its special working part cross-section, which has been reduced by 13 percent compared with the standard needle. The geometry of the EcoStar® thus creates a narrower contact angle of the fibers in the barb and thus achieves a higher fiber retention capacity. A perfectly coordinated interplay between the clothings in the field of Carding achieves an optimal carding result both in the revolving flat card and in the roller card. The use of special clothing geometries in the nonwovens industry, like the worker and doffer wires SiroLock® and EvoStep® leads to better fiber control and a more even web. The SiroLock® card clothing also impresses with increased performance of the roller card, while EvoStep® card clothing focuses on saving raw material. For the spinning industry, Groz-Beckert offers metallic card clothings, flat top and stationary flat clothings, as well as flexible strips. For processing synthetic fibers in particular, the company offers a special card clothing with a curved tooth profile: the synthetic doffer wire D40-30-52C CBF.
This achieves a better fiber transfer from the cylinder to the doffer, thus creating an improved yarn quality and higher efficiency of the revolving flat card.
