摘要:
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).

The invention consists of a nipper apparatus for use in a comber comprising a nipper frame (1) having a cushion plate (2) fixed to its lower portion, said nipper frame being suspended as a whole by a nipper pivot (6) and a nipper shaft (4) and being arranged to swing toward and away from a detaching roller (10) by a reciprocating turn of said nipper shaft, said nipper apparatus being arranged to repeat gripping and releasing of a fleece (17) on said cushion plate by means of a nipper knife (12) by causing a nipper arm (11) having said nipper knife at its front end and a spring rod (14) at its rear end to turn according to a swing of said nipper frame (1), in which a spring end portion (14a) of said spring rod (14) which serves as a point for providing pressure support for said nipper arm is supported movable with respect to a machine frame, said spring end portion being moved to a predetermined position according to a change in a nipper gauge and refixed in that position.

This invention relates to a method and apparatus for automatically cutting and removing a small diameter lap bobbin (3) comprising passing a small diameter lap bobbin (3) which is clamped on its end surface by a lap bobbin holder (7) between a pair of feed rollers (5,6) of a lap feeder (1) which we spaced apart from each other; moving downward the lap bobbin; cutting a lap sheet (4) by the tension of the lap sheet (4) at that time; releasing the clamp of the bobbin (3); dropping the bobbin (3) to a deliver device (9) and discharging the bobbin (3).
摘要:
A differential gear mechanism (G) for driving a detaching roller of a comber is driven by two driving systems (D₁ , D₂); a driving system (D₁) which converts a constant-speed rotation motion (R) of a drive transmitted thereto into a variable-speed rotation motion through a crank mechanism (C₁) and a quadric crank mechanism (L) and transmits the variable-speed rotation motion to the input shaft of the differential mechanism (G); and a driving system (D₂) which converts the constant-speed rotation motion of the drive transmitted thereto into a swing motion by a crank mechanism (C₂), converts the swing motion into a reciprocating motion by connecting rods and linkage, and transmits the reciprocating motion to the planet pinion of the differential gear mechanism. A feed motion curve of the detaching roller given with the differential gear mechanism is an ideal curve such as that obtained by an ideally designed cam comber.
