A system for opening and closing a mixing manifold includes a drive motor, a cam plate, and a valving rod connector. The drive motor imparts movement in first and second directions. Movement imparted in the first direction causes the cam plate to move linearly in a third direction and movement imparted in the second direction causes the cam plate to move linearly in a fourth direction. Movement of the cam plate in the third direction causes the valving rod connector to move linearly in a fifth direction and movement of the cam plate in the fourth direction causes the valving rod connector to move linearly in a sixth direction. Movement of the valving rod connector in the fifth direction causes retraction of a valving rod of the mixing manifold and movement of the valving rod connector in the sixth direction causes extension of the valving rod.

A system holds a roll of film that includes a core and film wound around the core. The system includes a rod having an outer diameter that is smaller than an inner diameter of the core, a proximal wing located on the rod and configured to rotate about the rod, and a distal wing located on the rod and configured to rotate about the rod. Each of the proximal and distal wings includes contact surfaces configured to contact diametrically-opposed locations on a side of an inner surface of the core and non-contact surfaces that span between the contact surfaces of the wing. The non-contact surfaces of the wings do not contact the core if the core has a cylindrical shape. The distal wing is capable of rotating around the rod independently of the proximal wing.

A system includes a dip tube, a feed line, and a check valve. The dip tube is inserted through an opening in a source of chemical precursor and into the chemical precursor in the source. A portion of the feed line is located in the dip tube. The feed line passes out of the dip tube. The chemical precursor is capable of flowing out of the source through the feed line in a downstream direction. The check valve is located in the portion of the feed line in the dip tube. The check valve permits the chemical precursor to pass substantially only in the downstream direction. The feed line is coupled to a transfer pump that draws the chemical precursor out of the source through the portion of the feed line in the dip tube.

A method and apparatus for sealing a plastic enclosure is provided. The apparatus includes a handle including elements pivotally coupled together at a first end. The apparatus also includes a heating element positioned along an inner surface of an element and connected to a power source where a longitudinal axis of the heating element is oriented parallel with a longitudinal axis of the element. Plastic material including first and second plastic layers is positioned at an interface between the second elements. Upon pivoting the first elements from an open position to a closed position the heating element increases a temperature at the interface to melt the plastic material and form a seal between the first and second plastic layers.

A continuous skin packaging and coating apparatus and a coating method for tablets. The continuous skin packaging and coating apparatus comprises a lower coating film unreeling roller, a waste edge reeling roller, an upper coating film unreeling roller, a lower coating heating component, an upper coating heating component, a first mold provided with a first table placing hole, a second mold provided with a second tablet placing hole, a heat-sealing plate, a cutting component, a blank tablet implanting component, and an operating mesa. The lower coating film unreeling roller and the waste edge reeling roller are provided on either side of the operating mesa. The lower coating film heating component, the blank tablet implanting component, the upper coating film unreeling roller, the upper coating film heating component, the heat-sealing plate, and the cutting component are sequentially provided above the operating mesa. The first mold is provided under the operating mesa below the blank tablet implanting component. The second mold is provided under the operating mesa below the heat-sealing plate. The upper coating film heating component is provided below the upper coating film unreeling roller.

The embodiment provides a heat-sealing apparatus and a method of accurately controlling heat sealing temperature by measuring the temperature using a heat-sealing apparatus which heat-seals a pair of heat seal materials by nipping them between a pair of heating bodies. The method of heat-sealing includes mounting a cover material on the surface of at least one of the heating bodies to be in contact with the heat seal material, attaching a minute temperature sensor to the surface of the cover material on the side to be in contact with the heat seal material, and controlling temperature of welding face by the temperature detected by the minute temperature sensor, and an apparatus therefor.

An induction heating sealing device for induction welding of a packaging material for producing sealed packages of pourable food products in a package producing machine is provided. The packaging material has at least one layer of metallized film. The induction heating sealing device comprises an AC power source and an inductor coil connected to the AC power source and configured to induce eddy currents in the metallized film for inductive heating of the packaging material, wherein the AC power source is configured to generate a variable-voltage or current signal of a frequency higher than 1 MHz.

A longitudinal sealer includes a housing, an arm, and a heating element. The housing is configured to be installed in a foam-in-bag system. The arm is movably coupled to the housing. The heating element has a leading edge exposed through an exterior surface of the arm. A position of the arm with respect to the housing is controllable so that the arm is movable between a first location where the leading edge of the heating element is not in contact with a film in a film path of the foam-in-bag system and a second location where the leading edge of the heating element is in contact with the film in the film path of the foam-in-bag system.

A packaging machine, comprising a control unit, at least one measurement device and a plurality of work units for different processes. One of the work units is designed as a sealing station which comprises at least one moisture sensor designed as the measurement device which is functionally connected to the control unit and is designed to detect moisture within the sealing station as a time-dependent measured variable during a program sequence of the sealing station. The program sequence may comprise an evacuation process, wherein the control unit is designed to calculate a rate of change in the moisture during the evacuation process of the sealing station. The control unit may abort the evacuation process performed on the sealing station, based on the rate of change, before reaching a target vacuum pressure within the sealing station, immediately or after a specified delay time elapses.

There is described a unit (1) for forming/advancing at least one pack (3) or at least one portion of a pack 5 (3), comprising: a frame (12a, 12b), at least one carriage (14, 14b), which is movable along a path (13a, 13b) with respect to frame (12a, 12b) and is adapted to form/advance said pack (3) or said at least one portion of a pack (3), an electromagnetic stationary device 10 (50), at least one tag (52a, 52b) carried by carriage (14a, 14b), and wireless communication means (51) configured to establish a bidirectional communication between stationary device (50) and tag (52a, 52b).
