A yield in the step of bonding two members together is improved. A bonding apparatus includes a stage capable of supporting a first member having a sheet-like shape, a fixing mechanism capable of fixing one end portion of a second member having a sheet-like shape so that the second member overlaps with the first member, and a pressurizing mechanism capable of moving from a side of the one end portion of the second member to a side of the other end portion and spreading a bonding layer under pressure between the first member and the second member. The first member and the second member are bonded to each other.

The methods herein relate to assembling an elastic laminate with a first elastic material and a second elastic material bonded between first and second substrates. During assembly, an elastic laminate may be formed by positioning the first and second substrates in contact with stretched central regions of the first and second elastic materials. The elastic laminates may include two or more bonding regions that may be defined by the various layers or components of the elastic laminate that are laminated or stacked relative to each other. In some configurations, a first plurality of ultrasonic bonds are applied to the elastic laminate to define a first bond density in the first bonding region, and a second plurality of ultrasonic bonds are applied to the elastic laminate to define a second bond density in the second bonding region, wherein the second bond density is not equal to the first bond density.

A composite manufacturing system for aircraft structures is provided. The composite manufacturing system comprises a tool for forming a composite structure, a vacuum bag, and a tool base. The tool comprises cured composite planks and layers of flexible material. The cured composite planks run parallel to each other. The layers of flexible material are positioned between and bonded to the cured composite planks. The vacuum bag surrounds the tool and is configured to apply pressure to the tool during curing of the composite structure. The tool is configured to deform in response to the pressure and prevent poor quality laminate and/or anomalies from developing in the composite structure during curing. The tool base is configured to hold the tool in place as it deforms.

A manufacturing device of a membrane-electrode assembly for a fuel cell bonds each of anode and cathode catalyst electrode layers continuously formed in upper and lower electrode films to upper and lower surfaces of an electrolyte membrane. The device includes: upper and lower bonding rolls respectively installed to upper and lower sides of a transport path of the electrolyte membrane and of the upper and lower electrode films, the bonding rolls pressing the catalyst electrode layers to the upper surface and the lower surface of the electrolyte membrane at a predetermined temperature to be transferred, and upper and lower adsorbents respectively disposed at the upper and lower sides of the transport path in an entry side of the upper and lower bonding rolls, installed to be reciprocally moved along the transport path, and selectively adsorbing the upper and lower electrode films.

A joining device includes a pair of cylindrical rotors 210 and 220, holding surfaces 211 and 221 of which for holding a pair of sheet-like members 30, respectively, have a width smaller than a width of the pair of sheet-like members 30. The joining device has a conveyance unit 200 which superimposes the pair of sheet-like members sequentially while conveying the pair of sheet-like members, by rotating the pair of cylindrical rotors, and joining units (first joining units 300) which join portions of the superimposed pair of sheet-like members to each other sequentially, the portions protruding beyond the holding surfaces of the cylindrical rotors.

The present disclosure relates to apparatuses and methods for assembling elastic laminates that may be used to make absorbent article components. Particular aspects of the present disclosure involve an anvil and a spreader mechanism adjacent the anvil. During the assembly process, a first substrate may be advanced in a machine direction onto the rotating anvil. The spreader mechanism operates to activate an elastic material by stretching the elastic material in the cross direction to a first elongation. The elastic material is then consolidated to a second elongation in the cross direction, wherein the second the elongation is less than the first elongation. The consolidated elastic material is then bonded between a first substrate and a second substrate on the anvil. In some configurations, the first and second substrates may be nonwovens, and the elastic material may be an elastic film and/or an elastic laminate.

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods and apparatuses herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.

A wafer bonding apparatus including: a lower chuck to which a lower wafer is secured at a peripheral portion of the lower chuck; an upper chuck to which an upper wafer is secured; a bonding initiator for pressuring a central portion of the upper wafer until the central portion of the upper wafer reaches a central portion of the lower wafer, thereby initiating a bonding process of the upper and the lower wafers by deforming the upper wafer; and a bonding controller for controlling a bonding speed between a peripheral portion of the upper wafer and a peripheral portion of the lower wafer such that the upper wafer becomes un-deformed prior to bonding the peripheral portion of the upper wafer and the peripheral portion of the lower wafer.
