Improvement of Foil Packet Transfer Between Wheels in YB25 Soft Packer

In YB25 soft packer,the assembling error of cam affects the synchronization of foil packet transfer between the No.2 and No.3 wheels due to wide fluctuation range of clamping clearance,which results in the staggered label wrapping.The location of setting holes and fixtures for cam setting were improved and applied to 10 YB25 soft packers.The results indicated that the clamping clearance between the No.2 and No.3 pushers was reduced from 1mm to less than 0.3mm and the packing quality of cigarette packet was improved obviously.
