摘要: A top-comb driving mechanism applied to a conventional combing machine, wherein cycles of forward amd rearward reciprocal swinging displacing motions of a nipper body of each combing head are carried out, is provided with a motion transmission mechanism each one round rotation of a driving shaft in synchronism with a combing cylinder to each top-comb holding arms in a condition such that the reciprocal upward and downward swinging motion of a top-comb holding arm is created so that the above-mentioned forward end rearward reciprocal swinging displacing motion of the nipper body is combined with the above-mentioned reciprocal upward and downward swinging motion of the top-comb holding arms of each combing head, whereby each top-comb is reciprocally displaced along a locus of a forward displacement thereof which is a gentle convex curve directed slightly downward, and displaced along a locus of a rearward displacement thereof which is a gentle concave curve directed slightly upward, between a front terminal point of the forward displacement motion and a rear terminal point, located a little higher than the front terminal point, of a rearward displacing motion thereof.

摘要: An improved combing cylinder utilized for a combing machine provided with a fringe control member having a chevron shaped cross section and a forwardly inclined surface sloped toward the cylindrical boss of the combing cylinder, with respect to the direction of rotation of the combing cylinder. The fringe control member is rigidly mounted on the combing cylinder at a position downstream of the needle segment of the combing cylinder, in a condition satisfying the timing whereby the tip line surface of the fringe control member closely faces the bottom detaching roller when the detaching rollers start to change their direction of rotation from a reverse rotation to a normal rotation. The radius of the forward end of the fringe control member is made smaller than the radius of a peripheral surface of the tip end of the combing needles of the needle segment, so that a recessed portion is formed adjacent to and behind the last alignment of combing needles of the needle segment.
