LMC-V, LMI-V
Yarn Length Meter

Measuring range 1 – 999999 cm or inch
Electronic length meter to measure the yarn consumption of a single yarn feeding system for one or more machine cycles of a circular knitting machine.

Measuring time is determined with start/stop signal of the magnetic sensor or manual by operator

Special Features

  • Yarn length meter LMC-V for measurements in cm and LMI-V for measurements in inch
  • Sensor controlled unit with a sensor (mounted on machine frame) and magnet (mounted on rotating part) for automatic start/stop signal
  • Precision, ball-bearing mounted wheel is recessed into an adjustable slot on the rear side
  • Material slip is eliminated by maximum enlacement of material (approx. 120°) with rubber coated wheel

It is stationary mounted between filament break monitors and filament guides using the supplied magnetic base.

 Standard Features

  • Easy to operate
  • Includes magnetic base for quick installation on the machine; it is stationary mounted on the zylinder ring between filament break monitors and filament guides
  • Battery operated length meter

OPERATION

In ”Auto” mode a permanent magnet is mounted to a revolving part of the machine. The sensor supplies the start/stop signal. The predetermined number of revolutions (from 1- 99 rev. set on the rotary switches at the front side) are counted and the cumulated yarn consumption is displayed.
In ”Basic” mode the unit works without external sensor; Operator determines measuring time by pushing start/stop button.

Advantage of yarn length meter LMC-V and LMI-V use:

  • Continued measuring of the yarn consumption of all knitting feeds ensures uniform stitch lengths and hence homogeneous fabric structure.
  • Predetermined fabric specifications can be reliably maintained and repeated.
  • The quantities of each type of yarn which are required for producing particular fabrics can be simply and accurately calculated.
  • The use of LM ensures the same fabric quality, respectively structures can be produced on different machines in the same quality.
