Slitting Dates Back Quite a While {In The History of Tape Making

Created in England from the early 1800’s, commercial papermaking was a enormous catalyst to the creation and advancement of industrial rewind slitting equipment. Quickly thereafter rewind slitting technology grew slowly as brake, clutch and mechanical abilities became accessible.

Transfer things forward Two centuries, today’s modern technologies such as the usage of servo powered devices instead of clutches and electronic drives that keep track of unwind, slitting and rewind tensions even though the equipment is functioning. Additionally, at which technologies have really taken hold is definitely the use of automated slitter knife set up devices where operator can easily program their slit widths and as a consequence may easily confirm the appropriate slit width through normal quality checks.

Contract Slitting

Advancements to slitting capabilities that have powered change include driven unwind systems, load cell tensioning and infrared web diameter detectors. In effect to handle large parent rolls and push the web through the rewind slitter, many will use driven unwinds. For webs which are affected by tension immensely, the application of load-cells are essential to even out problems those webs can present. Finally, the use of infrared systems to keep track of unwind diameters is useful in maintaining tensions consistent as a roll starts off large and heavy and gets lighter and smaller throughout the running process.

In rewind innovations over the years, the use of continuous wind and turret wind systems have been huge time savers to the rewind process. After the set of material has run to the proper length, the web is cut, the set is moved on to a convey, the next set of papercores is picked up by the core chucks, and the next set starts the rewind process again. Meanwhile, the finished set can be packaged as needed. On a turret wind system, the rewind system has two sets of shafts, so while one shaft of rolls is finishing, the other set will turret in and after the finished set is cut, it turrets away and the rolls get pulled off the rewind. In this process, the stoppage time is less than 5 seconds.

Finally, on the unwind side of the equipment, the use of automatic roll changing equipment has reduced stoppage time as well.

For some converting companies today having the latest and greatest in rewind slitting equipment helps to reduce setup costs, increase productivity and ultimately make more earnings. Firms that utilize a number of these technologies are poised to be successful in the future.
