Karl Mayer Develops SMR-B Sizing Machine
Karl Mayer Rotal S.r.l., Italy, a subsidiary of Germany-based Karl Mayer
Textilmaschinenfabrik GmbH, has engineered the new SMR-B – (OH -) sizing machine, which features
the MPC-PW prewetting system.At just 2 meters long, the machine can carry out prewetting and sizing
in a small space. The unit features a linear roller arrangement for ease of use, quick loading, and
easy correction of yarn breaks or winds.One or two MPC units can be fitted on the machine,
depending on the number of yarns processed and the width of the machine. According to the company,
prewetting increases sizing performance and also reduces the hairiness of the yarns, facilitating
processing of more yarns.
The MPC-PW prewetting unit features seven rollers.During sizing, the yarn is dipped and
squeezed twice to improve sizing agent adhesion and to maximize yarn hairiness reduction. To ensure
the yarns are treated as gently as possible, a guide roller has been eliminated between the MPC
prewetting unit and sizebox, and the number of rollers on the MPC has been reduced from 13 to
seven. The SMR-B – (OH -) can be computer-controlled and monitored by touch-screen controls.
