    Abstract: An apparatus makes plastic bags in succession by intermittently feeding webs of plastic film longitudinally along a path. Movable units are spaced apart along the path and are driven by drive units, one for each movable unit, longitudinally of the film webs. Control switches, one for each movable unit, works on each drive unit to move the corresponding movable unit for position adjustment. The film webs are processed by at least some of the movable units whenever being fed intermittently, to successively make the plastic bags.

    Abstract: The invention is a mounting system for a vibrational element. The vibrational element has a longitudinal axis, an outer surface and an axial displacement node. The mounting system includes an isolation member which has an isolation surface, an isolating body, and an engaging portion. The engaging portion is immovably secured to the isolation member and extends radially inward from the isolation body at a point radially opposite the isolation surface. The engaging portion is disposed so as to engage the outer surface of the vibrational element. Radial displacements of the vibration element are substantially decoupled from the isolation surface through the engaging portion.

    Abstract: A process and device are used to weld plastic sheets with hot gas. Conventionally for welding with hot gas, the gas was conveyed over an electrically heated body. However, temperature fluctuations occurred that were difficult to correct and the result was a relatively high power consumption. In order to make a precise temperature guidance with a favorable efficiency possible, the gas is blown through a tubular heat conductor (10) with outlet openings (16) in its circumference wall and against a plastic sheet, and the tube body (10) is heated by an electrical current that is controlled by at least one temperature sensor exposed to the temperature of the tube body and/or the hot gas. Preferably, the tube body (10) itself is used as a temperature sensor, while its resistance, which changes with the temperature, is used to control the current intensity.

    Abstract: This relates to a sealing head for sealing lids to cartons. The sealing head is provided with suction heads or cups for receiving a lid from a lid supply and depositing such lid in position on a carton which is mounted in a nest. The sealing head is provided with a seal member which forms the seal with a nest carrying a carton so that a vacuum may be drawn within the nest both within and around the carton. Thereafter, the sealing head provides an inert gas, such as nitrogen, to fill the carton with the inert gas, after which a support further sealing head moves the sealing head down further so that a lower edge of a projecting induction heating coil will clamp a lid against a carton and effect a heat bonding of the lid to the carton. The sealing head is self contained and has a fitting including a plurality of electrical prongs and fluid line sockets for coupling the sealing head to a receptacle. Finally, the induction heating coil of the sealing head is of a special configuration so as to compensate for a pull tab carried by the lid, which lid is generally oval to match the oval carton. The outline of the coil deviates slightly from the oval shape so as to provide a seal which has a starting point to initiate peeling of the lid from the carton. Further, this starting point is aligned with the pull tab and there are current compensating pins carried by the coil to compensate for the metal within the pull tab.

    Abstract: An ultrasonic rotary horn for continuously bonding together two or more layers of thermoplastic materials such as woven and nonwoven fabrics and films. The horn is adapted to resonate in a manner such that: 1) the excited end moves substantially in phase with the movement of the source of excitation; 2) the opposing end, whether or not it is actively excited, moves substantially out of phase with the movement of the excited end; 3) the radial work-contacting surface of the horn also moves substantially out of phase with the movement of the excited end; and 4) the horn exhibits a single nodal point at its geometric center. The horn has a concave configuration which comprises a central, circular flat portion which is concentric with the rotational axis and a convex portion between the flat portion and the radial surface. The convex portion is a curved surface having axial symmetry and a curvilinear profile in cross-section through the rotational axis.
