Ultrasonic welding method, structure welded by ultrasonic welding method, and ultrasonic welding device

A pair of thermoplastic resin members are placed on an anvil. A pressing force of a tool horn vibrating ultrasonically in a direction not perpendicular to but along upper surfaces of the pair of thermoplastic resin members is applied to the upper surfaces. The application of the pressing force of the tool horn vibrating ultrasonically allows melting of a vicinity of the upper surfaces of the pair of thermoplastic resin members. A welded structure part is formed on an unwelded structure part, thereby welding the pair of thermoplastic resin members as an overlap structure including the welded structure part arranged on the unwelded structure part. The distance and positional relationship between the pair of thermoplastic resin members after the welding are unchanged before and after the welding. The surfaces, placed on the anvil, of the thermoplastic resin members are neither burned nor discolored.

Film securing apparatus and method

Systems, apparatuses, and methods to secure a film to a container are provided. An example sealing device utilizes film from a supply of film to seal a lid onto a container. Various sizes of containers are usable with some example sealing devices. Additional features, such as printing on the film and piercing the film for ventilation and/or insertion of a straw are contemplated. One or more markings along the film may be utilized for confirming that an approved film has been loaded into the sealing device. In response, various components or features of the sealing device may be appropriately enabled or disabled. The one or more markings may also be utilized to convey data to the sealing device regarding the installed film, such as for improved operation thereof.

METHOD FOR MANUFACTURING FOAM MAT HAVING PRINTED LAYER ON ITS SURFACE
20230339154 · 2023-10-26 ·

A method for manufacturing a foam mat having a printed layer on its surface includes the steps of: stacking a plurality of foam sheets in a foaming mold; forming a printed layer by printing a layer of ink on a top surface of an uppermost one of the foam sheets or a bottom surface of a lowermost one of the foam sheets or both; and heating the mold for foaming the foam sheets at a same foaming rate of 2 to 3.5 times. The ink of the printed layer does not fall off. The printed layer can beautify the surface of the foam mat and prevent dust and dirt from accumulating on the surface of the foam mat.

In one method, a piece of nonwoven PET or PP fabric is formed into a tote bag using a bag forming device. Seams of the tote bag are ultrasonically welded using an ultrasonic bag welding device. The ultrasonic bag welding device includes at least one sonotrode. In another method, BOPP film is received and a full-color graphic is printed on the BOPP film for each tote bag using a printer. The printed BOPP film is received from the printer and nonwoven PP or PET fabric is received from a roll of nonwoven PP or PET fabric using a laminator. The printed BOPP film is laminated to the nonwoven PP or PET fabric. The printed BOPP film laminated to nonwoven PP or PET fabric is received from the laminator and a finished version of each tote bag is produced using an ultrasonic bag welding device.

Bag with coloured sheet for repairing composite panels, and colouration and repair method

An assembly includes a bag and of a composite panel exhibiting a damaged region to be repaired by polymerization of a repair piece using the bag. The bag includes a sheet intended to be laid over the panel. When the panel and the sheet are laid one atop of the other, the sheet exhibits regions capable of absorbing heat emitted by radiation onto it in a proportion that is dependent on the polymerization temperature needed for that region of the panel that corresponds to it, the radiation being partially absorbed by suitable colouration of the sheet in the region concerned. Determining those regions of the panel in which radiation is less well absorbed than in others means that the heating can be adapted to suit the needs of polymerization in terms of repair and that even polymerization can thus be obtained over the entire damaged region, thereby consolidating the repair.

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.
