An automatic laminating apparatus includes: a lay-up head provided with a raw-cloth roller on which a thermoplastic prepreg is wound and a pressing device for pressing the thermoplastic prepreg drawn from the raw-cloth roller against a lamination surface; and a welding device provided with a welding head pressed against the thermoplastic prepreg to temporarily weld the thermoplastic prepreg to the lamination surface, the automatic laminating apparatus laminating the thermoplastic prepreg by performing a lamination operation of moving the lay-up head to lay the thermoplastic prepreg having a predetermined length on the lamination surface, in which the welding device is provided in the lay-up head, and the automatic laminating apparatus further comprises a drive control device that causes the welding device to perform temporary welding of the thermoplastic prepreg laid in the lamination operation in a course of the lamination operation.

Automatic laminating apparatus having welding device

A guide mechanism includes a support member that supports a plurality of tow guides provided corresponding to each of fiber bundles, and a support mechanism that supports the support member with respect to an arm, and the support mechanism is configured such that the support member is displaceable in a width direction orthogonal to an extending direction of the arm in a plan.

Automated fiber bundle placement apparatus

A cutting mechanism includes a cutter roll and a rotational driving mechanism for rotationally driving the cutter roll. The cutter roll has a roll body and a blade portion protruding from a peripheral surface of the roll body. The blade portion is formed at a same position on a circumference of the roll body and extends in an axial direction of the roll body. The cutter roll is arranged so that the axial direction is at a predetermined angle with respect to a pull-out direction of the reinforcing fiber material. The cutting mechanism further includes a slide mechanism that displaces cutter roll in the axial direction toward a side in the pull-out direction of the reinforcing fiber material at least when the reinforcing fiber material is cut.

Feed device for reinforcing fiber material and method for cutting reinforcing fiber material by using the feed device

A method of knitting a single knit fabric comprising the steps of successively advancing a plurality of needles corresponding to a non-knitting section within which a yarn from a yarn feeder forms a transit yarn portion beginning with a needle on the side of a starting point of the transit yarn portion to lower the yarn from the yarn feeder below the needles, and engaging the yarn from the yarn feeder by another needle on the side of the yarn feeder closer to the yarn feeder than the advanced needles.
