  • Publication number: 20240300190
    Abstract: A fiber placement apparatus for arraying prepreg tapes in a width direction, and laminating the arrayed prepreg tapes includes first rollers and a second roller. Each of the prepreg tapes is a material of a fiber reinforced plastic. The first rollers feed out the prepreg tapes one by one. The first rollers rotate around first rotation axes. The second roller arrays the prepreg tapes, fed out from the first rollers, in the width direction, and feeds out the arrayed prepreg tapes slidably. The second roller rotates around a second rotation axis lying on a skew position with respect to each of the first rotation axes. At least one first roller of the first rollers is provided with a first position adjustment mechanism that adjusts a position of the at least one first roller in a first rotation axis direction of the at least one first roller.

  • Publication number: 20240100786
    Abstract: A roller unit aligns tapes in a width direction and feeds the tapes in a length direction while pressing the tapes in a thickness direction. The tapes are made of fibers which have not been impregnated with resin or have been impregnated with the resin. The roller unit includes rollers and a support shaft. The rollers rotate by friction force between the tapes and the rollers. The rollers are aligned so that rotation axes lie on a same straight line. Maximum diameters of the rollers are same as each other. The support shaft supports the rollers rotatably at rotational speeds independent from each other. Each of the rollers includes springs and thereby has elasticity. Length directions of the springs as well as expansion and contraction directions of the springs are radial directions of the each of the rollers. The springs are radially disposed inside the each of the rollers.
