Cigarette filter production apparatus and control method for cigarette filter production apparatus

摘要

Task: To enable the control of the cigarette filter production apparatus with a simple method and at the same time to prevent the lowering of the product quality of the cigarette filter due to variations in the setting of the cigarette filter production apparatus. [Technical Solution] The cigarette filter production apparatus is equipped with a plurality of fiberizing roller pairs, a transport roller pair, a coil tube part forming the tow band, and a control part that controls the peripheral speed of the most downstream fiberizing roller pair. The control part calculates from the rod residual curl RCR (plug) corresponding to the weight ratio of weight WT1 per unit length of the tow band in the state of dissolved crimping and weight WT2 per unit length of the tow band stuffed into the rod, from the output speed VKDF of FIG Tow bands from the winding tube portion and from the peripheral speed V2 of the most downstream fiberizing roller pair, the tow band residual crimp RCR (V2) in the most downstream fiberizing roller pair and controls the peripheral speed V2 so that this value corresponds to the tolerance value M1 ,
