CTC International is introducing its Model SHDL-900-EG Edge Guided Heavy Duty Constant Tension Unwind Stand. The unwind stand can handle a variety of materials, including tag, label, board, film paper, foil and other materials used in packaging and converting applications. The heavy-duty double end supported design allows rolls as large as 40 inches diameter to be accommodated. Rolls are unwound from a removable air shaft supported at both ends by safety locking chucks. The stand features an integral roll lifting system using two heavy duty air cylinders and a minimum number of parts, and is capable of lifting rolls exceeding 850 lbs. The “closed loop” pneumatic tension control system utilizes a generously sized web festoon whose position proportionally controls a heavy duty pneumatic braking system, providing precise web tension. Web tension is easily adjustable while running. Options include splicing table, web pen marking system and “end of roll” indicator. The machine is customizable for a variety of diameters, web widths and core sizes and can be manufactured to meet CE compliance.
