Equipment for cutting particularly a paper web with a water jet

摘要

Support and positioning means (10) and a cutting head (13) supported on them extend in the operating position of the area of the edge part (14') of a paper web (14). In the cutting head (13), there is a support surface (16) and at least one nozzle (17), which is set in such a way that the edge part (14') travels between the support surface (16) and the nozzle (15). The equipment includes mechanical cleaning means (20) and/or a cleaning construction (21) for keeping the support surfaces (16) clean. The cleaning means (20) and/or cleaning construction (21) are arranged on the opposite side of the paper web (14) to the nozzle (17).
