1st April 2009, Obertshausen - Modern lace
production requires high-tech solutions at every stage of the manufacturing
process and that is why Karl Mayer is constantly improving and revamping its
range of lace raschel machines and coming up with new innovations in warp
preparation at the same time. One of the latest innovations to come from the
renowned manufacturer of warp preparation equipment is the PBW 130/2 pattern
beam warping machine.
Karl Mayer claims that this new machine offers optimum
productivity, process reliability, ergonomic features and top-quality winding.
The advantages claimed have been achieved by extensively revamping and
optimising the machine design.
Higher productivity through innovation
The patented friction drive at the circumference of the
pattern beam is equipped with just one roller, operates slowly by means of a
frequency-controlled three-phase current motor, and has been combined with a
newly developed electromechanical traversing drive. The synchronised operation
of the two drives permits yarn laying to be carried out so as to achieve
precise cross-winding when building up the package. The high reverse
acceleration and controlled stroke shifting at the reversing points also enable
a perfect edge to be produced, without any raised edges on the package. Pattern
beams featuring bi-conical precision winding and a stable construction are
produced.
Further features of the high-quality beams include active
calculation of the winding conditions and optimum guiding of the yarn using the
principle of constant yarn spacing to the run-in point. According to Karl
Mayer, the new PBW 130/2 operates quietly and at a higher warping speed than
its predecessor, and is equipped with a modern control system. The
human/machine Interface (HMI), which is operated via a 3.5" touch screen,
enables all the relevant warping parameters to be input easily, and permits
information relating to the production process to be called-up .
Applications
The PBW 130/2 is particularly suitable for the simultaneous
warping of two pattern beams having different yarn spacing values. The beam
length is 330 cm or 130", ‘System Mayer’, and the maximum diameter is 140
mm. The associated creel is a standard creel with 128 take-off points arranged
in eight levels, each having 16 packages. Karl Mayer says that the infinitely
variable warping speed of 0 to 400 m/min makes the new, efficient PBW 130/2 to
an indispensable piece of equipment for producing short runs and test fabrics,
as well as for large-scale production.
