Apparat zum Rechtwinkligmachen von Muffen.

摘要

An apparatus for squaring a sleeve (10) having at least one pair of opposed bevelled corners comprises a cradle (44) having sleeve supporting members merging towards an apex but terminating spaced from the apex and having a support beam (46) in the space between the members and the apex. The support members and support beam are arranged to conform with the outside shape of the sleeve in squared condition. An platen (66,68) is moveable into a sleeve while the sleeve is supported in the cradle. The platen is shaped to substantially conform with the inside of the sleeve in squared condition and is moveable toward the apex to force the sleeve into conformity with the cradle and the support member and thereby square the box. Preferably an end closure pad applicator (78) will apply an end closure pad (26) to the squared sleeve while supported in the cradle and with the platen in place to resist pressure applied to the outside of the sleeve when the pad is being secured to the sleeve.
