A lap holding mechanism for a comber for performing good combing and piecing functions in a state in which noises and vibrations are restrained without using a cam mechanism, wherein a nipper frame (3) is disposed above a combing cylinder (1), wherein a cushion plate (4) is mounted on the leading end portion of the nipper frame (3), wherein the cushion plate (4) holds a lap (Lp) in cooperation with a nipper member (7), wherein the leading end portion of a driving arm (12) is rotatably connected to the rear end portion of the nipper frame (3), wherein the proximal end portion of the driving arm (12) is fixed onto a nipper shaft (11) rotatable in clockwise and counterclockwise directions, wherein two fixing supports (14, 15) are disposed above and below the nipper frame (3), respectively, and a four-joint link mechanism having two movable supports (20, 21) each having in turn a follower link (19) as a connecting joint is provided between the two supports (14, 15), wherein the front portion of the nipper frame (3) is rotatably connected to the follower link (19), and wherein the nipper frame is oscillated by virtue of the cooperation of the nipper shaft (11), the driving arm (12) and the four-joint link mechanism (17, 18, 19). |
