A handle supporting a mat roller head at an angle to the handle to make applying force to the adhesive acoustic damping mat easier in tight spaces. The angle is optionally adjustable. The roller head includes arms supporting a roller with a two-dimensionally corrugated surface to enable applying adhesive acoustic damping mats to irregular surfaces. Additionally, the roller head supports two LEDs to improve visibility of the workspace when adhesive acoustic damping mats are being applied. Power for the LEDs comes from batteries in a battery compartment in the handle. The screw-on battery compartment cap includes an ON/OFF switch. The handle has a top thumb rest and a bottom finger rest and has a partial tactile engagement surface.

A stretchable elastic film is interposed in a stretched state between a first sheet layer having no elasticity and a second sheet layer having no elasticity. Heat melt energy is applied to a region of a large number of bonded portions spaced apart from each other by a heat melting apparatus from the outside of the first sheet layer and the second sheet layer to melt the elastic film. The first sheet layer and the second sheet layer are bonded directly or via an elastic film at the large number of bonded portions. The elastic film is caused to pass through the counter roll and the nip roll to pass along the counter roll and then pass along the anvil roll. The elastic film is stretched by making the circumferential speed of the anvil roll faster than the circumferential speed of the counter roll.

Ultrasonic welding is performed by passing a first sheet layer, a second sheet layer, and an elastic film interposed therebetween in a stretched state in a machine direction between an anvil roll having a large number of protrusions and an ultrasonic horn. The anvil roll includes a region having the protrusions and in the region. A site, in which welding is performed by one ultrasonic horn, has a portion in which an area rate of the protrusions changes in a roll circumferential direction and a roll length direction. A difference between a maximum value and a minimum value in a change of the area rate of the protrusions in the roll circumferential direction is 4.5% or less, and a difference between a maximum value and a minimum value in a change of the area rate of the protrusions in the roll length direction is 1.5% or less.

A method for producing a breathable web, comprising: feeding a web on the surface of an anvil roller rotatable about its axis and having a plurality of welding protrusions cooperating with a welding element, welding said web at a plurality of welding spots on head surfaces of said welding protrusions and forming respective annular welding seams at said welding spots, about respective welding projections, and respective thin membranes located within said annular welding seams and adjacent to the head surfaces of said welding protrusions, and removing said thin membranes after said welding by means of a peeling roller having an outer surface tangent to said head surfaces of said welding protrusions.

The present invention relates to a device for producing a reinforcing structure, which comprises a fiber-reinforced strip having a thermoplastic material, onto a molded body surface. The device is characterized in that emission direction vectors of at least two laser diodes of a laser diode array are aligned in a non-parallel manner to one another and are directed toward one another in the direction of a heating surface of the strip and/or the molded body surface.

The present disclosure relates to methods and apparatuses configured to bond elastic laminates together between a rotating drum and anvil. The drum includes a fluid nozzle and a press member. As such, a first elastic laminate and a second elastics laminate may be advanced in a machine direction onto the rotating drum. A fluid is heated to a temperature sufficient to partially melt substrate layers of the first and second elastic laminates. As the drum rotates, the press member shifts radially outward from the drum wherein a length, L, of the pattern surface extends in the cross direction across a plurality of elastic strands of first and/or second elastic laminates. And the partially melted portion of the substrate layers of the first and second elastic laminates and the plurality of elastic strands are then bonded together by being compressed between the pattern surface and the anvil roll.

Provided is a printing-lamination inline system and method being suitable for manufacturing packages having various kinds of package designs in small quantity and being capable of performing inkjet printing and lamination in an inline manner. The printing-lamination inline system comprises: a first web-shaped base material supply unit configured to supply a first web-shaped base material; an inkjet printer of a single-pass system, which is configured to subject the first web-shaped base material to aqueous inkjet printing; an adhesive application unit configured to apply an adhesive to the first web-shaped base material subjected to the aqueous inkjet printing; a drying unit configured to dry the applied adhesive; a second web-shaped base material supply unit configured to supply a second web-shaped base material so that the second web-shaped base material is bonded to the first web-shaped base material; and a lamination unit configured to subject the first web-shaped base material and the second web-shaped base material to lamination.

A fixing device for fixing an elastic sheet and a low-stretchable sheet via fixing parts while superposing the sheets in a thickness direction includes: a rotating member including protrusions on an outer peripheral surface to form the fixing parts and rotatable along a transport direction; and a sandwiching member arranged at a predetermined position of the rotating member in a rotational direction, and sandwiching the sheets by a surface portion in cooperation with each of the protrusions to form the fixing parts when each of the protrusions passes through the predetermined position, the surface portion being larger than a top surface of each of the protrusions. At a sandwiching position in which the sheets are sandwiched cooperatively by the sandwiching member and the rotating member, the low-stretchable sheet is located between the elastic sheet and the top surface of each of the protrusions of the rotating member.

Apparatus and methods for impinging a heated fluid onto the surface of a substrate and then locally removing the impinged fluid. The apparatus and methods may be used to heat a surface of a substrate e.g. so that the substrate can be melt-bonded to another substrate.
