METHODS AND APPARATUS TO FACILITATE PLASTIC FILM PROCESSING
A system includes a film processing module, a processor, and memory. The processor and memory are in communication with the film processing module. The processor is configured to dynamically coordinate movement of the film processing module relative to a moving web of film and to perform a function on the web of film with the film processing module.
System and method for sealing a plastic enclosure
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.
Apparatus and method for making inflated articles
A sealing device generally includes a rotatable support cylinder having an outer, circumferential surface and a heating element disposed about such surface and secured thereto such that the heating element rotates therewith. The heating element is coiled about the outer surface of the cylinder in the form of an overlapping helical pattern. Juxtaposed film plies may be sealed together by bringing the sealing device into rotational contact with the juxtaposed film plies and heating the heating element to a temperature sufficient to cause the film plies to seal together.
Hermetic sealing device for packages containing food products
The sealing device, forming the object of this invention, for packages containing food products, includes a unit for gripping and/or feeding a piece of thin flexible material forming a film used to cover and at least partly seal the food product; a sealing element which includes a rheostat having an annular body and two terminals extending from the annular body and connectable to a voltage generator capable of generating and maintaining an electrical potential difference at the ends of the two terminals in such a way as to cause to flow along the rheostat an electric current capable of heating the annular body to a predetermined sealing temperature. Each terminal has at the point of its connection to the annular body of the rheostat a cross section whose surface area is the smallest compared to the cross sections at all other points of the terminal.
Apparatus for bonding overlapping material layers
An automatic bonding apparatus and a method for thermally induced seam bonding of weldable and/or gluable flat flexible material layers with each other which are each configured as a material web, material band and/or material piece and arranged so that they overlap at least partially wherein the bonding is performed by an electrically controlled contact heating arrangement through a heating wedge welding method. A temperature and/or a power of the heating wedge which is formed by a thin folded steel sheet blank is controlled as a function of a relative velocity between the material layers and the automatic bonding apparatus. This is performed so that a thermal energy that is transferred from the heating wedge to the material layers to be glued is kept constant. For this purpose the relative velocity is detected and the power of the heating wedge is automatically adjusted when the relative velocity changes.
Thermal caulking method, thermal caulking device, and caulked material
Provided is a thermal caulking method of melting, at one time, a plurality of bosses 33 of a second member 30 protruding toward an inner circumferential surface of a conical hollow portion 11 of a first member 10 while being fitted to a plurality of holes 132 provided in the inner circumferential surface of the hollow portion 11 of the first member 10 having the substantially conical hollow portion 11 so that the plurality of bosses are joined to the first member 10, in which the plurality of bosses 33 are melted at one time by using a heat chip 51 having a continuous shape in the circumferential direction of the hollow portion 11 along the inner circumferential surface and are joined to the first member 10 while the adjacent melted bosses 33 are connected to each other.
Bagging mechanism for trash bags and smart trash receptacle
The present invention discloses a bagging mechanism for trash bags and a smart trash receptacle. The bagging mechanism is disposed within a body of the trash receptacle. A first fixed edge and a second fixed edge intersecting the first fixed edge are provided at tops of internal surfaces of the body of the trash receptacle. The bagging mechanism includes a first pressing bar, which is able to slide along the second fixed edge to gather the open end of the trash bag onto the first fixed edge, and a second pressing bar, which is able to slide along the first fixed edge to gather the open end of the trash bag onto the second fixed edge. The first pressing bar and the second pressing bar are further able to work together to gather the trash bag to the intersection of the first fixed edge and the second fixed edge. In the vicinity of the intersection, a heat fusing device is disposed for heat fusing and sealing the trash bag. The bagging mechanism further includes driving means for driving the first pressing bar and the second pressing bar to move. With this arrangement, the issue that conventional smart trash receptacles do not have an automatic bagging mechanism or are only capable of semi-automatic trash bagging, with insufficient bag sealing, insecure sealing and low loading capacity can be solved.
FOAM-IN-BAG SYSTEMS AND COMPONENTS THEREOF
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.
HEATING DEVICE FOR A HEATING AND SEALING SYSTEM
A protective packaging formation device is disclosed herein. The device includes an inflation assembly that directs fluid between first and second overlapping plies of a web material. The device also includes a sealing mechanism that includes an arcuate web-support surface. The web-support surface includes a heater that defines a heating zone that is operable to heat the plies to create a longitudinal heat seal that seals the first and second plies together as the web is driven over the heating zone in a downstream direction. The web-support surface also includes a cooling zone disposed downstream of the heating zone operable to allow the heated plies to cool at the longitudinal heat seal as the web is driven over the heating zone in a downstream direction, such that the cooled longitudinal heat seal retains the fluid between the plies.
SYSTEM AND METHOD FOR SEALING A PLASTIC ENCLOSURE
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 pair of spaced apart heating elements positioned along an inner surface of an element and connected to a power source where a longitudinal axis of the heating elements 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 elements increase a temperature at the interface to melt the plastic material and form a pair of spaced apart seals between the first and second plastic layers.
