A rotary impulse sealer for forming a series of discrete bonds in a bondable material. The rotary impulse sealer has a roller rotatable about an axis. The roller has a roller body and a plurality of seal bars extending radially outwardly from the roller and spaced apart around the roller body. At least one of the seal bars has a body and a selectively heatable heating element extending along at least a part of a length of the seal bar body. The roller is rotatable through a pre-heating pressure application region in which the at least one seal bar is adapted to apply pressure to a bond area of the bondable material, followed by a heating region in which the at least one seal bar is adapted to heat the bond area, the regions being stationary with respect to the rotation of the roller. A method of forming packages containing fluid or fluent material includes continuously providing at least two sheets of bondable material having a fluid or fluent material therebetween, applying pressure to a transverse bond area of the bondable material to force the fluid or fluent material away from the transverse bond area, and heating the transverse bond area to form a seal.

A system (300) for closing mailers includes a forming funnel (320) and a fusing device (310). The forming funnel includes funneling surfaces that receive an opening of a mailer in an insertion direction (302) and constrain the opening of the mailer after the opening of the mailer is inserted. The funneling surfaces are arranged to continue constraining the opening of the mailer as the mailer moves in a sliding direction (304). The fusing device includes a slot that receives the constrained opening of the mailer from the forming funnel. The fusing device applies pressure and heat to the opening of the mailer as the opening of the mailer moves through the slot. The pressure and the heat applied by the fusing device cause portions of the opening to fuse together to close the mailer.

A method of manufacturing a pouch type secondary battery according to an exemplary embodiment of the present disclosure includes the steps of: accommodating an electrode assembly in a space between an upper case and a lower case; and thermally fusing edge parts of the upper case and the lower case to each other, wherein edge parts of the upper case and the lower case each include a substrate layer, a metal layer and a sealing layer that are sequentially stacked, and wherein before the step of thermally fusing, the method further includes forming a plurality of grooves on one surface of at least one sealing layer of each of the upper case and the lower case.

Methods for modifying contours of substrate surfaces are disclosed. Methods include depositing filler material on a critical mating surface of a substrate so as to render the mating surface more mateable with a matching substrate. The filler material can be deposited within or around features or defects on the mating surface such that a final desired surface contour is achieved. In some cases, the final surface contour of the mating surface is planar. This can prevent gaps associated with the features or defects from forming between the substrate and the matching substrate when they are joined together. The final surface contour of the mating surface can be determined by comparing dimensions of the mating surface to dimensions of a reference surface. In some cases, ink jet printing techniques are used to deposit the filler material accurately in prescribed locations and with precise thickness control.

The invention relates to a method for applying a material (30) to a fiber composite component within an application region (13) of the fiber composite component, the fiber composite component being produced from a fiber composite material having a fiber material (11) and a matrix material (12), the method comprising the following steps: providing at least one monofilament woven fabric (20), in which a plurality of or all threads each consist of a single filament, arranging the at least one monofilament woven fabric (20) on a fiber preform (10) in the application region (13), which fiber preform is formed from the fiber material (11) of the fiber composite material, curing, in a common process step, the matrix material (12) of the fiber composite material, which matrix material embeds the fibers material (11) of the fiber preform (10), and a matrix material (12) embedding the monofilament woven fabric (20), thereafter the matrix material (12) of the fiber preform (10) and the matrix material (12) of the monofilament woven fabric (20) being at least partially cured, tearing off the monofilament woven fabric (20) integrally bonded to the fiber preform (10), andapplying the material (30) in the application region (13) after the monofilament woven fabric (20) has been torn off.

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.

Methods of bonding a first object to a second object, including the steps of: providing the second object having a protrusion; providing the first object having a thermoplastic material; positioning the first object relative to the second object such that an assembly of the first and the second object is formed; applying a relative force between the second and first objects and applying mechanical vibration to the assembly of the first and the second object until at least a flow portion of the thermoplastic material becomes flowable and flows around the protrusion; and causing the thermoplastic material to re-solidify. The first object may be a connecting element including a feedthrough, wherein the second object has a corresponding opening. The protrusion may be deformed such that the protrusion has an undercut relative to an axis along which the first and second objects are pressed against each other.

A method for connecting two aircraft components composed of thermoplastic composite material by a rivet. The two aircraft components are arranged, in sections, areally on one another, before bores in the two aircraft components are expanded by a mandrel element such that the bores, after the expansion, form one continuous bore for receiving the rivet. Here, the two aircraft components are locally warmed by the mandrel element such that, during the expansion of the bores, the components are thermoplastically deformed. The mandrel element is inserted through the first bore into the second bore. The rivet is introduced into the continuous bore. A system for carrying out the method is also disclosed.

A method attaches a liquid-repellent filter to an air vent of a resin molded article accommodating a component/electronic part. A thermal processing tip and a thermally welding tip and a molded article are provided. The thermal processing tip (22) forms a filter attachment surface (14) at the inlet or outlet of an air vent (16) in a thermoplastic resin molded article (13). A filter fixing rib (15) is formed around the attachment surface. The porous filter (18) is dropped onto the filter attachment surface, and a thermal welding tip (2) is used to melt the filter fixing rib such that the melted resin flows onto and covers a circumferential edge portion of the filter, penetrating the body of the filter. The melted resin penetrating the filter 18 and covering the circumferential edge portion of the filter are cooled to solid, whereby the filter is fixed to the filter attachment surface.
