Wet wipes converting machines use 2 types of cutting unit. A simple, low maintenance, less expensive pinch or scissor cutter and a more mechanically complex roto-orbital disc saw. The first type is used when the ribbon to be cut is thin, usually less than 25 mm thickness. This is typical for lines shorter than 25 lanes and substrates thinner than 50 gsm. The second type is used in all the other cases, machines longer than 25 lanes, when the ribbon is thick and scissor cutter cannot guarantee a neat cut. In this case, a roto-orbital saw can cut easily and neatly 50 or also 80 lanes ribbon.

IMA Teknoweb improved its roto-orbital saw adding features which makes this unit faster (up to 600 cuts/min), more flexible (wider range of cutting length) and more reliable (less maintenance required). It consists of 2 rotating disc blades which match ribbon speed during cutting action and therefore guarantee a straight, neat, and squared cut.

It is based on patented system that includes a counter blade made of staves, placed in a straight belt. The counter-blade belt ensures high precision and reliability more than standard anvil drum.

Roto-orbital saw is currently proposed for all our long flat-fold lines (longer than 25 lanes) and is available for retrofitting existing machines.

IMA Teknoweb applies this techinolgy successfully also to dry wipes converting lines successfully. Main difference compared to wet wipes solutions is a lubrication device, which is necessary to limit temperature raise.
