In manufacturing a pleated stretchable composite member, a first sheet-like nonwoven fabric and a stretched cord-like elastic member (rubber thread, etc.) are positioned on the protruding surface side of a pattern roll, and a hot melt adhesive is intermittently applied to the stretched cord-like elastic member and the first sheet-like nonwoven fabric at locations where the protruding surface of the pattern roll is present, and then the stretched cord-like elastic member and the first sheet-like nonwoven fabric intermittently coated with the adhesive and a second sheet-like nonwoven fabric are integrally adhesively fixed at positions corresponding to locations where the protruding surface of the pattern roll is present. In the stretchable composite member, the valleys of the upward-facing breathers of the top-layer nonwoven sheet and the valleys of the downward-facing breathers of the bottom-layer nonwoven sheet are adhesively fixed via a stretchable elastic members (rubber threads) between the two nonwoven fabric sheets.

METHOD FOR PRODUCING SEPARATED STRIP-LIKE LAMINATE COMPONENTS COMPRISING AN ELECTRONIC COMPONENT EMBEDDED BETWEEN TWO LAMINATE LAYERS OF A TAPE LIKE ADHESIVE MATERIAL, AND DEVICE FOR PRODUCING SUCH LAMINATE COMPONENTS
20240100818 · 2024-03-28 ·

A method for producing separated strip-like laminate components including an electronic component embedded between two laminate layers of a tape-like material. Individual components are placed at defined intervals by a placement device onto a tape-like, lower first laminate layer moved in a conveying direction by a transport device, after which a tape-like, upper second laminate layer moved in the conveying direction is applied to the first laminate layer with embedding of the components to form a laminate tape. The individual strip-like laminate components are cut from the laminate tape by a cutting device having a movable cutting blade, which laminate components are picked up by a gripper device and transported away. The front end of the laminate tape is gripped by the gripper device in the region of a component and moved synchronously with the clocked movement of the transport device by a predetermined distance through the cutting device and positioned relative to the cutting blade. The actual position of the component in the laminate component in relation to the conveying direction is detected by a measuring device connected downstream of the cutting device. When a deviation of the actual position from a defined target position is detected, the synchronous movement of the transport device and the gripper device is controlled in dependence on the detected deviation.

METHOD OF MANUFACTURING A RACE BIB
20190318216 · 2019-10-17 ·

A race bib and a method of assembling the same. The bib includes a first and second layers with a programmable tag embedded between them. Indicia are provided on a first surface or a second surface of the first layer. A backer is positionable between the tag and the first or second layers. During assembly, a competitor number is printed on the first layer with an ink printer, a tag number correlating to or corresponding to the competitor number is encoded into the tag with a RFID tag printer. The printing and encoding can be accomplished by a combined printer. Alternatively, an optical scanner reads the printed competitor number and transmits the same to the tag printer. The second layer overlays the first layer and is thermally welded or adhesively secured to the first layer.
