Paper, textile, plastic sheet material linear measurement system - determines number of marks during longitudinal movement of material along belt via guide rollers

摘要

A measurement unit is provided, which determines the length from the longitudinal movement of the material being measured. The measuring belt (35) runs horizontally or inclined downwards in the longitudinal movement direction of the material (27) being measured. The belt is wider than the material line (27). The guide rollers (36, 37) of the belt are idler rollers, so that the material being measured moves the belt along with it in the same direction. The belt (35) has marks at a determined spaced pattern. The measuring unit (40), determins the number of marks during the longitudinal movement of the material (27) and by evaluation gives its continuous length. ADVANTAGE - Type system improved, measures total length also with strongly expandable or stretchable material such as curtain roll material.
