More Efficient Than Ever – The New JL 65/1 With Its Different Versions

OBERTSHAUSEN, Germany — June 27, 21012 — Lace is feminine, sexy and seductive, and is the result of
sophisticated, carefully considered, high-tech solutions. The Jacquardtronic® Lace machine is one
such example. The machines in this successful range of machines manufactured by KARL MAYER produce
lace with a smooth, fine, filigree appearance, can process different band widths without any
transition points, and are extremely efficient – and this level of performance has been improved
constantly. The result of the latest upgrade made to the Jacquardtronic® range was the optimisation
of the JL 65/1B. In this case, the development work did not only focus on making the machine
“faster and wider”.

Improved efficiency by increasing the working width and speed

The development work carried out by KARL MAYER involved making specific
modifications and changing the technical design, changes which considerably increased the
productivity of the Jacquardtronic® Lace with 65 guide bars.

These innovations on the new JL 65/1B and F models with a working width of 132″ enable them
to reach maximum speeds of 800 min-1, which means that they are 60% faster than their predecessors.
The older machines operated at speeds of up to 500 min-1.

Also in this range is the JL 65/1B with a working width of 168″ which, because of its overall
design, can reach almost the same speed as its sister machine with a width of 132″. It is more
efficient than the previous 132″-machine with its old design.The performance has been increased by
25%, just by extending the width of the new machine from 132″ to 168″.

The new machine concept also involved repositioning the pattern drive, with the string bars
being controlled from one side. This change enabled the performance potential to be fully utilised
for the relevant widths, and guarantees smooth machine running.As well as being extremely
efficient, the new JL 65/1B operates at the same high level of precision offered by all KARL
MAYER’s machines, and is easy to operate. All the operating elements are arranged ergonomically and
are also easy to see. Data can be transferred easily and clearly, either via an Ethernet interface
or touchscreen.

Huge patterning potential – as always

The JL 65/1B and F are fitted with electronically controlled systems for the yarn feed,
fabric take-down and pattern drive, as well as with KAMCOS® technology and its Motion Control/Multi
Speed system. These enable this multibar jacquard raschel machine to work a wide range of design
options. Clipped looks, muted, three-dimensional effects, and distorted grounds in a wide range of
structures and variations can be produced, as well as large-repeat pattern motifs and sweeping
contours processed in bourdon yarns. Different yarn materials can also be used to produce a greater
range of designs. Another advantage of the Jacquardtronic® Lace machine is that it is still
possible to change the starting position of the pattern quite freely – to make optimum use of its
patterning potential.

The latest optimised features have not reduced the patterning potential in any way. The
patterns that could be produced on the existing JL 65/1 with a working width of 132″ can be adapted
for processing on the new machine, simply by modifying the pattern data.Once again, the JL 65/1B is
being launched onto the market with the focus on versatility, productivity and technical

The first patterns produced by KARL MAYER’s product developers can be found in the Patterns
section of this issue.
