Strap welding system and method for welding two ends or sections of a strap around a bundle of articles or around a pressed bale. The strap welding system has a weld assembly for frictionally welding two ends of a plastic strap around a pressed bale. The weld assembly has a weld head with an upper weld jaw and a lower weld jaw, and wherein the lower weld jaw is supported, directly or indirectly, by a spring. A connecting piece for moving the lower weld jaw can optionally have a section with a connecting spring.

Side portions of a guide member mounting portion of the instrument panel include a panel side welding guide surface integrally formed therewith. The panel side welding guide surface is spaced apart from the back surface of the instrument panel. Side portions of the guide member include a guide side welding guide surface integrally formed with the guide member. The panel side welding guide surface and the guide side welding guide surface overlap each other. One of the guide side welding guide surface and the panel side welding guide surface includes a position regulating recess. The other of the guide side welding guide surface and the panel side welding guide surface includes a position regulating protrusion that fits into the position regulating recess during vibration welding.

A method of manufacturing a toy finger skateboard may include inserting a flange portion of a toy finger skateboard truck into a flange receiver of a toy finger skateboard deck. The toy finger skateboard truck is moved such that a column portion of the toy finger skateboard truck is received by a through hole of the toy finger skateboard deck, and then, the method involves interacting with a top end of the column portion of the toy finger skateboard truck to affix the toy finger skateboard truck to the toy finger skateboard deck. A portion of the top end of the column portion may be cylindrical. The top end of the column portion of the toy finger skateboard truck may be welded to a seat portion of the toy finger skateboard deck, and the welding may include spin welding.

There is provided a method for producing a metal-resin composite which includes a resin member and a metal member having a roughened surface in at least a portion of the surface thereof, the resin member being joined so as to be in contact with at least a portion of the roughened surface. The method includes a step of joining the resin member and the metal member by melting the resin member with the frictional heat generated in the surface of the metal member on its side opposite to the resin member in a state where the metal member and the resin member are superposed. The method includes making adjustment so that when the roughened surface is measured at arbitrary five points by using a confocal microscope according to ISO 25178, the developed area ratio (Sdr) is 5 or more in terms of number-average value.

A method for joining two components of a meltable material comprises the steps of providing a first component having a first border region and a second component having a second border region, placing the second component relative to the first component so as to form an overlap between the first border region and the second border region under a gap between the first border region and the second border region, continuously heating opposed sections of the first border region and the second border region at the same time through at least one energy source arranged in the gap at least partially, continuously providing a relative motion of the at least one energy source along the first border region and the second border region in the gap, and continuously pressing already heated sections of the first border region and the second border region onto each other.

A toy finger board kit includes a board and at least one shoe. Each shoe includes a finger hole in an upper of the shoe and at least one bracket on a sole of shoe. The at least one bracket is configured to removably attach the at least one shoe to the board. In some instances, the board is formed by inserting a flange portion of a toy finger skateboard truck into a flange receiver of a toy finger skateboard deck. Then, the toy finger skateboard truck is moved such that a column portion of the toy finger skateboard truck is received by a through hole of the toy finger skateboard deck. Finally, a top end of the column portion of the toy finger skateboard truck is affixed to the toy finger skateboard truck to the toy finger skateboard deck.

Structural support (1) including a first support portion (2) delimiting at least one containment compartment (4, 4′); a second support portion (6) at least partly in front of the containment compartment (4, 4′); and a sliding element (4), housed in the containment compartment (4, 4′) and interposed between the first (2) and the second (6) support portion. The sliding element (8) substantially consists of a thermo-processable fluoro-polymer with a melt-mass flow rate—according to the ISO 1133-1:2011 standard—of less than 5.0 grams/10 minutes, for example under 3.0 grams/10 minutes.

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).
