Overview:

The CHW (cantilevered hot-wire lap splicer) is Martin’s creative and effective answer to automatic splicing of non-wovens, tissues and extensible films. An integrated roll spindle/splice unit, hot-wire cut-off system and patented tension control system combine to offer the manufacturer using non-woven, tissues or extensible films incomparable value in automatic splicing and tension control.

The integrated roll-spindle/ splice unit allows in-aisle roll loading and splice preparation. The splice unit has been designed a s two separate halves, with one half of the splice unit attached to each roll-spindle structure. The roll-spindle/splice unit extends into the aisle allowing unobstructed roll leading splice preparation. A pneumatic lift carries the roll back into its running position.

A hot-wire cut-off system replaces the traditional knife cut-off system found on most splicers. This hot-wire system is a sale, clean and reliable alternative to knife systems. In addition, the CHW hot-wire system automatically trims the leading edge of a newly prepped web, ensuring a consistent tail-length.

The CHW is designed to run at tensions as low as .5 lbs total tension. A patented tension control system incorporated with either spindle drives or Martin’s unique braking system ensures tension accuracy within .25 lb total variation during running and splicing cycles.
