Abstract: Sliding-tongue compound needle comprising a needle (1) equipped with a hook (3) and with a sliding tongue (2) straddling the needle and equipped with an end (12) and with a shoulder (13), the bottom of the sliding tongue being longitudinally slotted in its distal region comprising the end (12) and the shoulder (13) so as to allow the end to be parted, the sliding tongue being movable relative to the needle to close and open the hook of the needle and to carry a stitch by its shoulder. This needle has means (6) for the vertical guidance of the sliding tongue (2) as it moves relative to the needle (1) so that the sliding tongue moves in a non-rectilinear path.

Abstract: A slider type needle for a knitting machine, comprising a needle (1) equipped with a beard (3) and a slider (2) having an associated length, a butt (4), a nose (5) and a stitch bearing shoulder (6), this slider being displaceable relative to the needle in order to close and open the beard of the needle and in order to permit the nose and shoulder of the needle to drive a stitch so as to execute a stitch transfer. The slider (2) has a U-shaped profile enabling it to straddle the needle (1). The slidcr is split (7, 15) in its end region, in order to allow an opposite needle or slider to pass through in order to carry out a stitch transfer or punching. This needle affords new knitting possibilities, in particular it makes it possible to carry out punching without an auxiliary section.

Abstract: The machine comprises two knitting beds (2, 3) and at least one pair of opposed cam carriers (4, 5). These cam carriers are independent and are driven individually, for example by notched belts (10, 13) and motors (12, 15). The elimination of the bow of the carriage makes it possible to provide a large number of bars (17 to 22) for yarn guides driven individually. The yarns arrive at the yarn guides along the shortest path, and the working speed can be increased considerably.

Abstract: Accurate control of the lateral position and spacing of a photosensitive medium is provided for recording a succession of lines representing graphic images or portions thereof, without mechanical edge guides. The apparatus includes an optical edge detector, a film drive assembly having two independently-controlled feed units, and a deviation correction means to correct the position prior to actual printing of images. Preferably, a triangulation method is used to electronically correct the drive path of the medium. Error-correction is obtained by the combined action of the two independent feed units operated by an electronic control circuit receiving signals generated by the optical edge detector. The apparatus also includes means to maintain the image receiving section of the photosensitive medium in a flat plane.

Abstract: The machine comprises a knitting head (2), a camholder carriage (3) and several striping bars (7), on which thread guides (6, 6a) are mounted between two movable stop blocks (9, 9a) and are equipped with a thread catcher (21, 21a) and driven by fingers (25, 25a). Auxiliary drive means (11) for the stop blocks and a mechanism for attaching the thread guides automatically to the stop blocks, detachable by means of the drive finger (25), make it possible at any moment to shift the thread guides together with one of these stop blocks independently of the movement of the carriage, thus making it possible to move away the thread catcher when it stops knitting, in the production of INTARSIA knitted fabrics.

Abstract: The camholder possesses at least one section having an axis of symmetry (A) passing through the center of a first sinker selection cam (14) and through the center of a needle transfer cam (25). The transfer cam (25) is retractable by means of a control device. Arranged on either side of the axis of symmetry (A) are sinker selection cams (15, 16), taker-up cams (17, 18), loom-style cams (19, 20) and transfer and receiving cams (21, 22). All these cams, arranged between the selection cams, are automatically retractable. The camholder has a single type of drop, and it makes it possible in one and the same drop to carry out both knitting and stitch transfer forwards or backwards and in both directions of movement of the carriage.

Abstract: Each needle groove formed in the needle bed of the knitting machine for slidably receiving the corresponding needle comprises a first dip registering with the major portion of the needle in the longitudinal direction, as well as a second, deeper dip engageable by a bent portion of the needle catch when this catch is retracted in the groove by a cam so as to clear the catch from the cam path, notably the path of the knockwing-over cam. When the needle is pushed by the key associated therewith or when this needle is selected in its operative position, the bent portion of the needle is raised by a ramp for engagement with the first, shallower dip.

Abstract: Rectilinear knitting machine comprising a frame consisting of two shaped bearing sections, preferably made of bent and soldered sheet steel, extending underneath the needle beds and equipped with vertical standards distributed along the shaped sections and supporting the needle beds with adjustable supports. This constructions enables the length of the needle beds to be increased, while guaranteeing their linearity. In addition, the space between the needle beds is freed for accommodation of rollers and a drawing device.

Abstract: A drawing device for a straight knitting machine comprises two belts capable of being continuously driven in opposite directions by respective drive shafts over two pulleys of small diameter. The pulleys are located in the area in which the stitches are formed and extend over the entire useful length of the needle rows of the knitting machine. The pulleys and thereby the belts are supported by pivoting frames and the belts are pressed one against the other by the rotation of their drive shafts. In use, knitting is drawn gently and continuously, with the possibility of sliding, between the belts, as the stitches are formed and quite close to the area in which these stitches are formed.
