The QMI SP-3500 Slit Vent uses sharp blades to create small slits in a continuously moving web. Movement of the web rotates the blade roll against a brush backup roll to create slits in the product.
KEY FEATURES INCLUDE:
- Individual blade holders that slide in a “T” slot and setscrew in place for nearly limitless slit location.
- Slotted aluminum sleeves slide over an internal roll.
- Brush back-up roll supports the film and allows proper blade penetration.
- The clamshell style enclosure opens and closes pneumatically and provides full safety guarding.
- 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.
- Can be mounted on a portable framework to allow movement from line to line.
