ABSTRACT:
This invention relates to an apparatus positioned within an automatic change-over system for cans at the exit of a drawing frame, gill box or similar machine. The apparatus prevents the escape of fibre sliver from the full cans, those latter being fitted with a semicircular strip pivoted at two diametrically opposing points below their upper rim. The apparatus has a mechanism for positioning the semicircular strip frontally forwards in the exit direction of the cans and a manipulator provided at its end with a gripper which embraces and grips the semicircular strip to raise it and arrange it above the can for the purpose of compressing the top layer of fibre sliver towards the inside of the can. This action prevents the sliver escaping from the full cans during their transportation to storage zones or during their distribution to the production departments for subsequent processing.
