Groz-Beckert latch needles guarantee the best fabric quality, including in the finest knits. Productivity is effectively boosted with high speeds. At the same time, Groz-Beckert latch needles can achieve energy savings which lower production costs.

The litespeed® needle is characterized by a partial reduction of the thickness of the needle shank on one side, the litespeed® plus needle by a partial reduction of the thickness of the needle shank on both sides.

The cut-outs on the needle shaft lead to less rubbing in the needle trick, resulting in lower machine temperature. High temperatures can reduce the speed of modern high-speed circular knitting machines. The use of litespeed® needles can effectively counter this and facilitate maximum machine speed. Another advantage of the litespeed® needle is the optimized lubricating properties, since the partial reduction of the needle shaft allows for better distribution of oil in the needle trick.

Costs are not only cut by the reduction in power consumption, lower maintenance and auxiliary costs resulting from less wear of all system components guarantee potential savings. The litespeed® needle furthermore enables longer service life. A welcome side-effect is significant reduction in CO2 emissions, brought about by lower energy consumption.

Groz-Beckert guarantees the best fabric quality even at very fine gauges with the most precise needle available on the market – the Vo-LC™.

The needle shines with high dimensional accuracy and numerous patented details, as well as proven Groz-Beckert product features such as G00 technology. The Vo-LC™ needle can produce ultra-fine knitted fabric with optimally uniform loop structure - and at maximum machine speed.

The special feature of the G00 hook is its low plastic deformation. This means that the hook breaks right after exceeding its limit of elasticity. The resulting fault is immediately recognized, the machine stops and the broken needles can be replaced. The G00 hook is used in particular when the needle hook must withstand unusually high amounts of stress, for example, from knots or slubs in the yarn or when special constructions are knitted.

With the transfer technique, high quality pierced patterns, also called Petinet patterns, can be manufactured on single-cylinder machines. Transfer needles have a transfer area in the form of a wing (= transfer wing) between the loop-forming part and the needle butt. This wing is an integral part of the needle shank. Supported by the transfer wing, a loop can be transferred from one needle to an adjacent needle on the same needle carrier. This makes transfer possible in one direction within the same needle carrier. The use of needles with spring plug in appropriate double-jersey machines enables transfer of loops from cylinder to dial and, if necessary, from dial to cylinder. Knitting components must be precisely aligned with one another for a secure transfer process. Moreover, knitting quality is significantly influenced by the uniformity and finish quality of the needle and the transfer clip.

By using Groz-Beckert spring-latch needles, complex knitting processes and high quality demands can be implemented on loop structure. This needle is one of the major innovations in the field of needle development and ensures high process reliability, as well as a high degree of flexibility with regard to pattern options and yarn employed.

Specifically when working with staple fiber in high-speed machines, much fluff is generated which mixes with oil and metallic debris and accumulates in needle cut-outs and grooves. The patented steel-plastic high-speed needle from Groz-Beckert provides the solution.

The shank closed at the lower edge and provided with humps at the upper edge effectively helps to minimize the accumulation of fiber residues between the needle and the bottom of the needle trick. This increases the intervals between cleaning cycles and significantly reduces defects like contamination-related vertical lines in the fabric. The user benefits from lower costs and increased productivity. The most effective solution is the combination of the special application needle SAN™ SF and the staple fiber sinker SNK SF.

When knitting staple fiber yarns in large diameter circular knitting machines, accumulations of fiber residues can result in deposits in the tracks of the needle and sinker carriers. Over time these deposits can result in uneven seating, tight movement and overheating of the needles and sinkers in the knitting machine.

The special shape of the SNK SF sinker with its opening in the front counteracts lint accumulation in the verge ring.

The most effective solution to reduce lint accumulation and significantly extend the time between cleaning cycles is a combination of the SNK SF sinker and the special application needle SAN™ SF. Increased productivity and reduced maintenance efforts are the result.

The requirements for selected parts are steadily rising because of higher machine speeds, higher system density and finer gauges. Nevertheless, optimized surfaces at crucial points, weight reduction and optimum setup of selected parts in close cooperation with mechanical engineers ensure functionality and safe selection.

The perfect interaction of needle and coupling part is ensured by close collaboration between mechanical engineers. Joint development projects provide for process reliability and high quality products.

In contrast to other coupling parts, the separator is not engaged. This means that it is not connected to the needle, but is located separately in the needle trick and can be separately moved.
