ABSTRACT:
A pivotable support (11) is mounted on the drive shaft of a main sawblade (2). Located at the bottom end of the support (11) is a preslitting sawblade (22) whose drive pinion (14) can be driven via a toothed belt (18) by a drive pinion (9) sitting on the drive shaft of the main sawblade. The support (11) is held by a tension spring (19) against an adjustable stop (21) provided on the housing (1). The device can also be attached subsequently to existing vertical board saws and ensures an absolutely clean cut even on plastic-coated chipboards and when using sawblades of inferior quality.
