Abstract: A serge applying assembly includes a sewing machine and a cutting assembly attached thereto. The sewing machine will sew the desired serge onto the edges surrounding a section of material by feeding the material between a pressure foot and a feed dog for engaging the material to be sewn and cut. A cutting assembly is included attached to the sewing machine proximate the sewing needle. The cutting assembly is able to engage the material and make a desired cut to aid the operator in applying serge around the perimeter of the material. The cutting assembly includes a pneumatic cylinder having a housing enclosing piston, with a blade mechanically connected to the piston of the pneumatic cylinder. The cutting assembly is attached to the sewing machine proximate the pressure foot, and is able to cut the material so that the operator can rotate the material for serge to be applied to a second edge of the material. This process is repeated until serge has been applied to the perimeter of the material.

Abstract: A reading device for use in a dobby having a peg cylinder connected to a heddle frame for operation thereof comprises a first bracket, a second bracket, a means for permitting physical contact between the first and second brackets and device to oscillate the second bracket so that the peg cylinder supported on the first bracket is moved to any of a normal, reversed and leveling positions.

Abstract: A card switching apparatus for a dobby comprises a bracket mounted for rocking motion around a shaft, a cylinder supported on said bracket and having a rotary shaft, a gear securely mounted on said rotary shaft of said cylinder, an input power shaft, another gear securely mounted on said input power shaft, and an idle gear interposed between the two gears, and that said idle gear has a rotary shaft which is supported for movement along a particular locus and which is moved in response to a rotational angle of a motor shaft.

Abstract: There is provided a program automaton for a weaving machine that includes means for effecting deweaving when there is more than one color in the repeat. The invention includes programmable counter means and a counter-switch. On deweaving, the counter means is decremented until it reaches zero. The counter-switch is then decremented one position while the counter means is reset and rapidly decremented to the programmed limit for the preceeding color in the repeat.

Abstract: A method and apparatus for synchronizing all heddle frames of a weaving machine which are operated by a punched-card-controlled dobby. The pattern card cylinder or the reading needles are moved to positions in which during a read, all the reading needles simultaneously engage the pattern card webs between the control points or the holes of the pattern card. Through this, the heddle frames are moved to the lower shed position by further operation of the dobby.In a preferred embodiment, the card cylinder is stopped in the center of the indexing movement effected by the driving projection of the drive shaft. The driving projection is laterally uncoupled from a ratchet gear by a hand lever and, simultaneously, further movement of the ratchet gear is prevented by the engagement of a locking member in a tooth space of the ratchet gear.

Abstract: The invention relates to dobbies of the type with double swinging levers and fastening hooks, provided with an auxiliary actuating system ensuring functioning for a weave different from that corresponding to the conventional reading device. To this end, a cam is provided, of such section that, by an angular displacement imparted after the momentary retraction of the disc of the reading device, the heel provided on certain of the hooks is pushed, causing said latter to pivot. The invention finds particular application in the textile industry.

Abstract: In a reading device for dobby or other weaving mechanism with double swinging levers and retaining hooks, of the type in which said hooks are actuated by a disc with radial lugs or the equivalent, at least one input gear connected for rotation with the shaft of the mechanism and meshing with an intermediate gear carried by a mobile member which can be displaced concentrically with respect to the axis of said input gear, and which intermediate gear meshes with an output gear in turn with the lug disc coupled for rotation and carried by a supporting lever associated with yieldable means operative to maintain said output gear in mesh with the intermediate gear, so that by selectively angularly displacing the mobile member about the input shaft, it is possible either to achieve a simple angular shift of the lug disc to allow for unweaving during reverse motion, or alternatively to achieve the retraction of said lug disc away from the heels of the hooks in order to level all of the heddle frames.

Abstract: An apparatus for reversing and racing a card in a dobby machine by using a planetary gear mechanism for reversing a card cylinder by a specified angle and operating a card handle fixed on the shaft, thus avoiding damage to the machinery even when operational errors occur.
