  • Patent number: 10052855
    Abstract: A laminating device for composite material includes a laser device, a hot roller assembly which has a first hot roller and a second hot roller, a cool roller assembly which has a first cool roller and a second cool roller, an axial roller-driving unit and a spring force-adjusting unit. The laser device provides a laser beam onto laminating surfaces of two separate composite materials prior to the hot roller assembly. The axial roller-driving unit drives the first hot roller and the second hot roller, and the first cool roller and the second cool roller, to undergo relative movement in a first direction. The spring force-adjusting unit provides spring forcing to the first hot roller and the second hot roller, and the first cool roller and the second cool roller, to ensure further the lamination of the two composite materials.

  • Publication number: 20180154586
    Abstract: A feeding device and a variable squeezing mouth are provided. The feeding device includes a first roller, a second roller and a middle guiding structure. The second roller and the first roller have a first zone therebetween. At least a part of the middle guiding structure is positioned in the first zone. The middle guiding structure has a passage being aligned with and connected to the first zone. The variable squeezing mouth includes a main body, a collet and a nut. The collet includes a base and at least two arms. The arms form a filament outlet. While the nut or the collet is moved with respect to the main body, the at least two arms and the nut are pressed against each other, so that a distance between the at least two arms is changed, and the size of the filament outlet is changed.

  • Patent number: 6195857
    Abstract: A device is designed to automate the process of stripping residual yarn from a yarn tube. The device comprises a feeding mechanism, an index dial, a residual yarn removing mechanism, a compression mechanism, and an arranging mechanism. The automated device enhances the recycling quality of the stripped residual yarn and minimizes the likelihood that the yarn tube is damaged in the stripping process.
