Paper tube cores are the critical components of the textile industry. Fabrics are winded on paper tube cores for further processing, transportation, etc. Paper cores come in standart widths and diameters, thus they need to be cut to fabric width sizes, on the textile operation premises. 

The paper core width, thickness and diameter, and the cutter speed & cutting quality are the critical parameters for this type of machines. The industry uses mostly 3” or 6” diameter paper cores. All the cutter designs have a long shaft, on which paper core is placed and the shaft is rotated by a motor. A blade which can shift sideways for width adjustment, cuts through the paper core. 

The problems with this typical design is that for 3” and 6” paper cores, it is needed to change the steel shaft mechanically or have 2 machines for a fast and efficient operation. The other issue is that when the blade travels a little further than the paper core, it contacts steel shaft and either is deformed or gets broken. As the blades are sharpened, the diameters of the blades are reduced. Thus, the blade travelling limit has to be increased to cut properly but not to contact the steel shaft. Also, for longer paper cores, the shafts get heavier and start bending or need support from the other end. This, either limits paper core width or the cutter machine investment cost increases dramatically. 

BTU-TECH has come up with a cutter design that solves all the above mentioned problems.
