Hans schmidt Vietnam - Yarn Length Meter LMC-V, LMI-V - - Thiết bị tự động hóa công nghiệp - ANS Vietnam

 

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.

• Length meter available for measuring cm (LMC) and inch (LMI)
• 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

• 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

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 comulated yarn consumption is displayed .

In ''Basic'' mode the unit works without external sensor; Operator determines measuring time by pushing start - stop button.

 Advantage of LM 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.
