A sealing device for sealing a lid material to sealing areas of a blister web comprises a first, heated sealing tool and a second sealing tool arranged opposite each other and movable relative to each other. A first intermediate element of elastic material is attached to the first sealing tool on a side facing the second sealing tool, and a second intermediate element of thermally-insulating material is attached to the second sealing tool on a side facing the first sealing tool. The first and second sealing tools are movable relative to each other between an opened position and a closed position, in which at least sections of the first intermediate element and of the second intermediate element exert pressure on each other. In the closed sealing position, the first intermediate element rests on the lid material and the second intermediate element rests on lands of the blister web.

A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.

The invention relates to an ultrasonic welding device comprising a sonotrode (14) transmitting ultrasonic vibrations and an anvil (15) disposed on an anvil carrier (17), the anvil (15) being disposed on the anvil carrier (17) in an exchangeable manner so that an mounting surface (21) of the anvil (15) rests against a support surface (22) of the anvil carrier (17) by means of a normal force exerted by a pretensioning device, the mounting surface (21) of the anvil (15) having a surface hardness greater than the surface hardness of the support surface (22) of the anvil carrier (17), the mounting surface (21) having a surface structure at least in the area of a partial surface, and the mounting surface (21) having a surface roughness of R.sub.z/R.sub.a≥2 at least in the area of the partial surface.

A compound heat seal structure that, when heat-sealing a bag with a stacked area level difference, reliably seals even a section having different level and that can be easily opened. A compound heat seal structure is provided as a peelable seal in a band shape on a bag and a linear heat seal is added as a peelable seal in that band-shaped peelable heat seal in the longitudinal direction thereof.

Various embodiments introduce a device for attaching a protection film, the device comprising: a fixing tray including a seating portion on which an electronic device is stably placed; a base portion including a coupling portion to allow the fixing tray to be attached to or detached from the base portion and at least one rail formed along the longitudinal direction or the width direction of the coupling portion; a roller portion which moves along the at least one rail and presses a surface of the electronic device stably placed on the fixing tray; and a hardening portion coupled to the base portion, closing or opening the seating portion of the fixing tray, and emitting ultraviolet rays toward the fixing tray. Other embodiments are also possible.

The invention relates to a method for applying a joint (2, 102) onto a plate (3), in particular a plate having shape defects. An edge of interest is defined on a portion of the plate (3) onto which the joint (2, 102) is intended to be applied. The plate (3) is then placed on a tool (4, 104) comprising a supporting element (5, 105) made of solid material and a supporting element (6, 106) made of flexible material, in such a way that the edge of interest rests on a portion of the supporting element made of flexible material. While the joint is applied onto the edge of interest, the plate is maintained in a predetermined reference position and the element made of flexible material is pushed against the plate, perpendicularly to an outer surface of the element made of flexible material, the outer surface being opposite to the surface on which the edge of interest rests.

To provide a method for readily forming an easily separable portion having an adhesive strength that is required as a package bag on packaging film, a package bag having an easily separable portion formed by this method, and a filling-packing machine utilizing this method. A method forming an easily separable portion in packaging film by interposing at least two packaging films between a horn emitting ultrasonic waves and an anvil oppositely disposed to the horn, and vibrating the packaging films by the ultrasonic waves, in which a vibratable layer is provided on the packaging film in at least one of the horn side and the anvil side.

Provided are a metal clad laminate and a method for producing the same. The metal clad laminate at least includes a thermoplastic liquid crystal polymer film and a metal sheet bonded to each other, wherein the thermoplastic liquid crystal polymer film has a surface with a glossiness (20) of 55 or higher in accordance with JIS Z 8741 on the opposite side of the bonding surface to the metal sheet. The method for producing a metal clad laminate at least includes: providing a thermoplastic liquid crystal polymer film 2 and a metal sheet 6; and introducing the thermoplastic liquid crystal polymer film 2 and the metal sheet 6 between a pair of heating rolls so as to laminate them.

An article having an embossed seal includes at least two webs, and an embossed seal joining a portion of the at least two webs, the seal including co-registered concentric discrete extended elements formed in the at least two webs, the discrete extended elements having open proximal ends.

A bonding device includes an upper chamber a pad with which a display substrate is pressable to a substrate; a stage between a lower chamber and the pad and including an opening through which air is introduced; a molding member between an upper chamber and the pad and surrounding the pad and the opening; and a support member connected to the stage The display substrate disposed on the molding member disposes first and second portions of the display substrate overlapping the planar and bending portions of the substrate, respectively, the molding member presses the first portion to the planar portion, and air introduced through the opening, expands the molding member to press the second portion to the bending portion.
