A two-piece cup is formed by a sidewall member having an upper edge, a lower edge, a pair of opposite side edges, a front surface and a back surface with the opposite side edges overlapped and sealed along an overlapped side seam, and a bottom member sealed along the lower edge of the sidewall member. The upper edge of the sidewall member is curled into a continuous rim. Upper corners of the sidewall member are formed with a plurality of parallel score lines extending inwardly from each side edge immediately beneath the upper edge, the score lines overlapping in the side seam.

A cup making machine has a bottom finishing station provided with a mandrel for holding a sidewall blank and a bottom blank such that a flap portion of the sidewall blank is folded around a lip of the bottom blank. The bottom finishing station has a seam clamp engageable with overlapped edges of the sidewall blank to form a side seam, and a clamp ring selectively movable into engagement with the seam clamp. The clamp ring includes an annular wall forming a recess for receiving a rotatable tool which presses against the flap portion and the lip to form a bottom seal. Part of the seam clamp protrudes into the clamp ring, and part of the clamp ring protrudes into the seam clamp to form a bridge acting against the overlapped side seam at the top of the lip.

An improvement in method and apparatus for continuously folding, heating, and tacking to the sides of the package panel the excess packaging material created by forming the package from a web of polyfoil material is disclosed. The method and apparatus is particularly useful in form, fill, and seal machines that form a plurality of aseptic sealed packages from a continuously advancing tube filled with a product, and incorporate a plurality of package receiving means mounted on a continuously advancing structure that forms sealed product filled packages into rectangular finished bricks by squaring the package, heating the excess material, folding the excess material against the package until it cools to thereby tack it.

A mechanically programmed indexing turret assembly configured to independently position each of a plurality of mandrels about a central axis of the turret for periodic interaction with a plurality of work stations. A central standard rotates at a substantially constant angular velocity. Each mandrel is mounted about the axis of the standard for rotation about a common axis therewith. The standard selectively transmits torque to the various mandrels in conjunction with cam and linkage elements. The respective periods of angular acceleration, deceleration, and absolute dwell of the respective mandrels are controlled in accordance with a predetermined cam contour associated with the cam track.

Improved clamp, seal, sever, and brick apparatus for use in form, fill, and seal machines that form a polyfoil tube filled with a product into a plurality of sealed packages, preferably aseptic packages. The improved apparatus incorporates a plurality of sealing heads mounted on a continuously advancing structure that transversely clamps, seals, and severs the endlessly advancing tube into packages, and compresses the packages to preform them into about their final rectangular configuration. Induction heating is used to seal the web. The sealing heads include a sealing jaw and an anvil jaw hinged together and adapted to clamp the tube therebetween at predetermined locations as the sealing heads and product filled tubing advance, the locations being adjustable and the sealing and anvil jaws being adjustable to control the volume of product clamped and sealed in each package.

A workstation for use with a turret type cup making machine is disclosed. The workstation is designed for sealing and finishing the bottom regions of paperboard style cups. A finishing wheel is mounted to a pair of nested housings that are configured to move the finishing wheel in a radially outward direction when one housing is rotated with respect to the other. Thus, the finishing wheel is moved longitudinally into the recessed bottom of a cup and then one housing is rotated with respect to the other forcing the finishing wheel radially outwardly until it contacts the bottom of the cup including portions of the sidewall blank and the bottom blank. This radial movement squeezes the cup bottom between the finishing wheel and an annular abutment wall. Meanwhile, the housings and finishing wheel are rotated together to drive the finishing wheel about the perimeter of the cup bottom to squeeze and seal the sidewall blank to the bottom blank.

A bottom expander for a flat bottom paper container of noncircular cross-section comprises a ring having an aperture surface for closely embracing the bottom rim of a container and plate-like tool elements, each having a radially outer edge surface which opposes and clampingly cooperates with that aperture surface. Each tool element is fastened to the front end of a leaf spring, the rear end of which is anchored in fixed relation to a support for the ring. The leaf springs support the tool elements in coplanar relation and so flex as to confine the tool elements to translatory motion that carries their outer edge surfaces toward and from the aperture surface, thus eliminating sliding guidance for the tool elements. The leaf springs also bias the tool elements to home positions in which they are spaced from the aperture surface.
