Converting Services Goes Back A Long Time {In The History of Foil Making

Conceived in England from the early 1800’s, commercial papermaking was a massive driver towards the invention and development of industrial rewind slitting machines. The application of mechanical brakes and clutches happen to be the pillar of many of the technology used for the 1st hundred and fifty years of the rewind process.

200 years afterwards, rewind systems have gone electronic by using servo powered magnetic motors and the analog dial has become replaced by electronic drive systems that keep track of tensions while machines are operating. Additionally, at which technology has really taken hold certainly is the utilization of automatic slitter knife set up methods where operator can program their slit widths and as a consequence can simply verify the appropriate slit width through normal quality inspections.



Technology improvements to improve rewinding abilities range from the usage of driven unwinds, load cell tensioning and dynamic web diameter devices. Some materials are extremely stretchy and unpredictable, the cabability to “push” the web through the winder is critical and this approach is used with driven unwind units. For webs that are affected by tension immensely, the usage of load-cells are essential to even out the difficulties those webs can present. Lastly, the usage of infrared systems to observe unwind diameters is helpful in maintaining tensions consistent as a roll starts large and heavy and gets lighter and smaller during 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. A continuous wind system winds the roll to a predetermined length, has a minor stop time to cut the web, push out the finished rolls, drop in the next set of paper cores and then starts the next set. Meanwhile, the finished set can be packaged as needed. While a continuous winder uses one shaft and has a slightly longer change from set to set, a turret winder uses a second shaft that turrets or spins into place after a set is done running. The time between is sets is about 5 seconds on a continuous winder

Lastly, on the unwind side of the equipment, the usage of automatic roll changing apparatus has reduced down time as well.
