The quality control is essential to guarantee product quality in the modern textile industry and the colour sampling of yarns can determine its effectiveness as the facts regarding the quality are derived from the inspection of the samples chosen.
The card winder
model colour sampling 74V
is the automatic equipment produced to prepare of yarn colour charts with measures of:
- Length: from 150 to 320 mm;
- Width: from 50 to 100 mm;
The colour sampling 74V wraps up to a maximum of 12 ends.
The setting of wrapping passages have to be set on electronic counter by the operator; once wrapping process has started the brushless motor increase speed with a gradual start, return and end rotation with a smooth deceleration until the end of the wrapping process.
Adjustable colours windings with external potentiometer for turning speed and wrapping speed;
Card speed range:
- from 50 to 850 turns/min;
Drawing up speed range:
- from 35 to 450 turns/min;
The instrument is supplied together with a auxiliary system to calibrate the tensile strength to the yarns
AUXILIARIES: Tension meter (0 - 400 cN) to adjust the tensile strength applied to the yarns
