Apparatus for forming a container

Abstract

An apparatus for forming a container is provided wherein the container is comprised of a side wall having a top bead and also a bottom member secured to the side wall with the side wall being formed from a blank which is wrapped with convolute form having side marginal portions overlapped and secured together. The apparatus includes means for forming the bottom member from a bottom member blank with the formed bottom member being carried by conveying means to various stations of the apparatus. A side wall feeder feeds side wall blanks through a side wall heater and to the conveying means for conveying thereby. A side wall wrapper is provided to wrap the side wall blank in convolute form about a mandrel and bottom member and secure overlapping marginal portions. A heater is provided to heat a bottom portion of the side wall blank and the bottom member so that same can be secured together during a container bottom forming operation by a bottom former which rolls a bottom portion of the side wall blank in overlapping relation to a skirt on the bottom member and then a bottom crimper is provided for finishing the bottom. The container in this form is then transferred to another conveying means which is operable to convey the partially completed container to a bead-forming means for forming a bead on the upper edge of the container. After this, the container is complete and ready for use.
