Karl Mayer launches tensioner for non-stretch glass yarns

Nov '13
The electronics sector is booming, as are all the sectors that supply it. The production and processing of fine glass filaments is one of the sectors that is profiting from the growing demand for electronic components.

These yarns, with their high elastic modulus, are used in the reinforcement layers of circuit boards.

Demand for them is particularly high in Asia, where they are being processed in increasing volumes. A new yarn tensioner has been developed by KARL MAYER to ensure that the best possible warps are produced for the subsequent manufacturing processes.

This new yarn tensioner in the AccuTense range is known as the AccuTense 0º Type C. It operates smoothly, handles the yarn gently, and is ideal for processing warp beams made up of non-stretch glass yarns. It can operate from a yarn tension of 2 cN up to a tension of 45 cN. The lower value defines the minimum tension for removing the yarn from the package.

The AccuTense 0º Type C can be used in all the current types of creels for processing filament yarns. This innovative device is mounted horizontally and can be fitted with a non-contact yarn monitoring system, without needing any modification.

The results of an internal customer survey of market requirements, together with the extensive expertise of KARL MAYER in the field of yarn tensioners, played a key role in the development of the AccuTense 0º Type C.

Design modifications

Like all the models in the AccuTense series, the AccuTense 0º Type C is a hysteresis yarn tensioner, which operates along the principles of eddy-current braking. The advantage of this is that the yarn is handled gently, since the thread is tensioned by an induction-dependent, rotating wheel and not by frictional points directly at the yarn itself. The wheel is the key element in this new tension control system.

It consists of a flat cylinder with tapering sides in the middle, and the conventional version is equipped with the AccuGrip surface on which the yarns run. The yarn is tensioned by being clamped at a 270º wrapping angle. With the AccuTense 0º Type C, the polyurethane AccuGrip yarn wheel is replaced with a version made from aluminium plated with hard chromium, and the design is also different. The new rotating ring is wrapped 2.5 to 3.5 times and produces the tension by adhesive force, rather than by the clamping effect as used to be the case.

This seemingly simple process is the result of extensive development work carried out at KARL MAYER. When wrapping is carried out several times, it is imperative that there is no clamping or superimposition between the ingoing or outgoing yarns and the wrapping yarns.

The side surfaces have been specially designed to ensure that the yarn layers are separated cleanly, i.e. there is a defined angle between the conical taper and the parallel holes. This means that the yarn runs into the yarn tensioner, moves by one layer thickness upwards for each revolution, and exits again without being damaged – and this principle offers many advantages.
