The QMI SP-3500 Slit Perforator uses sharp blades to create small slits in a continuously moving web. The unit is an economical choice for customers who do not need the intermittent operation and line speed following ability of the SP-3000. Movement of the web rotates the blade roll against a brush backup roll to create slits in the product.
- Slotted aluminum sleeves slide over an internal roll.
- Brush back-up roll supports the film and allows proper blade penetration.
- Designed for either in- or out-of-line operation.
- Can also be configured as a microperforation unit or as a combination of slits and perforations.
