With the joint efforts of the engineering team of GBCRANES and the Canadian R&P industrial product design company, the design of the new paper roll clamp has been completed, and its performance has been greatly improved compared with the first generation of paper roll mechanical clamps. Smaller diameter paper rolls, higher control precision, and important additional functions. A number of new patents have been applied for, and the roll jig has been concerned by 2 European users and is under commercial negotiation, looking forward to greater progress.
