Process for manufacturing inflatable bodies capable of assuming a desired complexly curved shape comprising two, around their circumference hermetically bonded opposing membranes (3, 4), which are internally linked by a plurality of link tapes (1), which tapes are bonded at an exact length and inclination angle at an exactly determined position. By numerical instructions, a continuous tape is fed and bonded alternately on the insides of the membranes by means of a roboticized tape positioning head, creating bond lines (2) between the tape and a membrane. Any fold occurring through local inclination, or planar angle variation of the tape relative to a membrane is kept between two bond lines on a membrane (3,4). A roboticized tape positioning and bonding head inside, and a bond activation head outside of a membrane can position relative to a membrane (3,4) by means of printed positioning marks, optical and proximity sensors to create the bond lines (2).

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.

Methods of tracing a lengthwise half of a board sports board and applying a substrate film cutout onto the board having the steps of centering a centerline of a tracing scale onto a center of the board, the tracing scale having an off-centerline on both sides of the centerline; aligning a centerline mark of the film with the off-centerline of the tracing scale; flipping the board over such that the board is on top of the film; tracing a trace outline of half of the board onto the film, such that the half of the trace outline is incrementally larger or smaller than the half of the board; removing a release liner from the trace outline to expose an adhesive in the film; wetting the adhesive with a solution of water and liquid soap; flattening the wetted film onto the board with a spreader; and wiping with a wiping cloth.

A description is given of a method for joining a first and a second film web (2, 2′) of a transfer film or laminating film, wherein the film webs (2, 2′) comprise a thermoplastic carrier film (21) and a decorative layer (23). Formed between the first and second film webs (2, 2′) is a common joining portion (3), in which the first and second film webs (2, 2′) are joined to each other by a welding process. A device for carrying out the method is also described.

The present disclosure relates to a method for splicing a web of packaging material, comprising: guiding the web of packaging material through a splicing device comprising one or more imaging devices, a slitter, and a sealing unit; acquiring a first set of images of one or more areas of the packaging material, storing the acquired first set of images, slitting the web of packaging material in one or more locations to form a tail end and a head end of a web of packaging material, aligning the head end and the tail end and superimpose one on the other in preparation for forming a splice, utilizing the imaging devices and the stored acquired first set of images to fine tune the alignment of the head end and the tail end, sealing the splice.

A method for producing a resin joined body in which a specific region L1 of a welding portion of a second resin member (21) is provided to form a low-laser-light-transmissible portion, and the low-laser-light-transmissible portion has a laser light transmissibility lower than that of a region of the welding portion other than the specific region L1. Welding is carried out so that a portion between points S2 and F2, serving as a weld overlap portion (112), is present in the specific region L1 forming the low-laser-light-transmissible portion. Also disclosed is a resin joined body.

A method of manufacturing a shell (36 and 38) of a wind turbine blade (10) is disclosed. The method comprises providing a mould (9) having a marker (11) at pre-determined locations. One or more layers of fiber fabrics are provided on surface of the mould (9) to form a shell half structure (36 and 38). Resin is infused through the one or more layers of fiber fabrics and subsequently cured to obtain the shell half structure (36 and 38). A reference portion (19) is marked on the shell half structure (36 and 38) to assemble one or more components on the shell half structure (36 and 38), by detecting a location of the marker (11) in the mould (9) by a detection device (13). The above method facilitates accurate positioning of component such as shear webs (7).
