Device and procedure for the slitting open of sacks

摘要

A device (10) for slitting sacks by means of rotating blades or disks (12) comprises a housing (14) which accommodates at least one mechanically drivable shaft (16) on which blades or disks are mounted. The housing (14) has an inlet opening (18), through which the filled sacks are fed mechanically or under the action of gravity, and an outlet opening (20), through which the slit sacks and the material released from the sacks can be carried away under the action of gravity. Furthermore, a movable restraining apparatus (24) is driven by a drive assembly from a first position in which the restraining apparatus is in a covered state and prevents sacks from reaching the at least one cutting member to a second position in which the restraining apparatus is in a released state and allows sacks to reach the at least one cutting member.
