Abstract: A method of automatically breaking and removing a nearly depleted lap (3), comprising steps of moving down the nearly depleted lap (3) held at the opposite ends thereof by a lap holding device (7) through the increased gap between the pair of lap rollers (5, 6) of a lap feeder (1), breaking the lap sheet (4) by applying a tension thereto, releasing the hold of the nearly depleted lap (3) to drop the nearly depleted lap (3) onto a conveying device (9), and carrying out the nearly depleted lap (3) by the conveying device (9), and an apparatus thereof.

Abstract: An automatic lap piecing method of piecing two lap sheets (2, 4) together, comprising the steps of holding the leading end (3) of the lap sheet (2) of a full lap (1) by a tubular member (6) by suction created in the suction opening (7) of the tubular member (6), shifting the tubular member (6) to a position where the leading end (3) of the lap sheet (2) can be superposed on the trailing end (5) of a preceding lap sheet (4), releasing the leading end (3) of the lap sheet (2) from the tubular member (6) to superpose the leading end (3) on the trailing end (5), and movign the tubular member (6) to smooth down the lap of the leading end (3) and the trailing end (5) to piece the two lap sheets (2, 4) together, and an automatic lap piecing apparatus capable of carrying out the automatic lap piecing method.

Abstract: A differential gear mechanism for driving a detaching roller of a comber includes two driving systems. One of the driving systems converts constant-speed rotational motion into variable-speed rotational motion through a crank mechanism and a quadric crank mechanism. The variable-speed rotational motion is transmitted to the input shaft of the differential mechanism. The other driving system converts constant-speed rotational motion into swing motion by a crank mechanism, converts the swing motion into reciprocating motion by way of connecting rods and linkage, and transmits the reciprocating motion to a planet pinion of the differential gear mechanism. The feed motion curve of the detaching roller produced by the differential gear mechanism is an ideal curve similar to that obtained by an ideally designed cam comber.

Abstract: An improved coiler device of a spinning machine, wherein a downstream portion of a coiler tube is further bent downward at a position adjacent to a place where a sliver exits, a flange extending upward is arranged in a coiler wheel side of a coiler plate, whereby an exit opening of the coiler tube is formed from a bottom face of the coiler wheel to the flange, and the coiler plate is movably constituted so that a relative speed of an inside face of the flange to that of the coiler tube is lower than a moving speed of the coiler tube.

Abstract: The front end portion of a cushion plate (5) provided on the front end of a nipper frame (4) is swung along an upwardly facing arc (25), i.e., an arc with an inner side facing away from the combing cylinder (3). The nipper frame (4) with the cushion plate (5) is constructed as a four-joint link mechanism which consists of the nipper frame (4), a nipper shaft (10), nipper frame setting fulcrum (7), nipper frame driving arm (11), and nipper frame swing arm (8).

Abstract: Can changing apparatus for drawing frame having at least one series of a can filling station and one or more empty can ready stations spaced at regular intervals, doffing means reciprocably disposed along the series of the stations to intermittently produce one cycle of reciprocation and having a series of pivoted arms identical in number and identically spaced with the series of stations. The apparatus further comprises means to swing the series of arms all simultaneously upright on retracting stroke of the reciprocation motion while keeping in horizontally swung down position on advancing stroke to thereby advance succeeding cans on the stations all together one stroke ahead of their former locations toward and away from the can filling station.
