Important technical details on the machinery: − the pulleys’ diameter − the operating speed − the required tension of the belt − the take-up type (screw type) − the take-up force − the spindle diameter − the transition distance − power and amps of the electric motor − the operating temperature − the needed coefficient of friction − the pulley diameter and the head pressure Calculating Length of a Winding Belt 1. Move the pulleys to the middle of the adjustable range in the horizontal plane; 2. Measure the distance between the centerline of the pulleys (I); 3. Calculate or measure the circumference of one pulley (Cp); 4. Calculate or measure the circumference of the desired tube (Ct); BELT LENGTH = (2 x I) + Cp + Ct DIMENSIONING OF THE BELT Every TUBEROLL belt is the result of several analysis related both to the Tube Winder Machines and to the produced Paper Tubes. For these reasons, in order to offer the best product, we require some additional information: Important technical details on the product: − type of paper, number of plies and width − the smallest tube diameter, inner − the smallest tube diameter, outer − the largest tube diameter, inner − the largest tube diameter, outer − the minimum wall thickness − the maximum wall thickness Important technical details on Tuberoll belt: − the width − the inner length − the overall thickness − the tensile strength − non-marking properties of the belt, if required In case Tuberoll belts replace a previous brand: − present belt type and producer − actual life in hours and quantity of produced tubes − type of failure, if any WIN WIN S.r.l.
