Abstract: Pouches in an interconnected strip are advanced edgewise to a cut-off station where the leading pouch is severed from the strip. Prior to being severed, the leading pouch is gripped by a transfer mechanism which lifts the severed pouch upwardly into pouch clamps carried on the opposing inboard runs of two chains adapted to advance the pouch broadwise through a filling section and along a path extending at right angles to the path of the pouch strip. Before being filled, the pouches are opened by shifting portions of the inboard runs of the two chains laterally toward one another and by pulling the side panels of the pouch away from one another with suction cups. The chains are adapted to be simultaneously adjusted in laterally opposite directions and through equal distances to enable the machine to be changed over to run pouches of different width while keeping pouches of all widths centered with respect to a common datum line as the pouches are advanced through the filling section.

Abstract: An intermittent motion horizontal packaging machine in which pouches made one at a time by a pouch making section operating at a high index cycle rate are filled two at a time while being advanced in a single row by a pouch filling section operating at one-half the index cycle rate of the pouch making section.

Abstract: Two face-to-face and continuously moving strips of heat-sealable material are guided around a drum adapted to rotate continuously about an upright axis and carrying a heated sealing ring on its lower end. The sealing ring is smaller in diameter than the drum and is offset radially inwardly from the drum in order to seal the bottom margins of the strips together without forming wrinkles in the seal.

Abstract: A carton blank may be folded by folder blades supported on an adjustable plate positioned on one side of a chain which carries a clamp by which the carton blank is pulled through the machine. After folding, the blank is glued to complete a flat shell and the shell is then inverted; the clamp is articulated so the shell may be turned in a horizontal plane to align a datum line on the shell to a datum line on a cartoner machine.

Abstract: Electric circuit breaker alternately providing overcurrent and/or over temperature protection by means of temperature responsive bimetal elements, whereby an increase in pressure as between electrical contacts is effected as the temperature may be increased up to the point of break, resulting in improved contact life and more effective contact when the device is subjected to external vibration.
