Karl Mayer Unveils New Transverse Draw-Off Creel
Karl Mayer Textilmaschinenfabrik GmbH, Germany, has introduced an optimized draw-off creel for lace
machines. The creel is the same size as its predecessors and is designed to hold standard bobbins
measuring 135 millimeters (mm) in diameter by 250 mm in length, but its new staggered row
arrangement of 20 horizontal bobbins by 18 vertical bobbins offers more reliable delivery of the
yarn to the lace machine, the company reports. Every second position in every creel row is left
empty, which produces a specific loading configuration with six packages situated around a large,
circular doffing area.
Yarn-tensioning elements were moved from continuous rails to short struts to allow easy access to the doffing area in order to change the bobbins. The new creel arrangement also permits more efficient circular ballooning limiters to be used, which increases reliability, Karl Mayer reports.
Typically, one string bar on a lace machine is attached to each creel line, with a normal repeat being 18 by 20 bobbins, so the 18-level arrangement of vertical bobbins also makes Karl Mayer's new creel highly compatible with lace machines featuring a greater number of string bars, the company reports.
