摘要:
Air feeding and control device for the pneumatic transporting of the weft (18-21) in air-jet weaving machines, comprising a control system (24), connected to air feeding means, which comprise a compressed air source (2) and a series of nozzles (14-17), driven by respective electrovalves (10-13) and which can be used for inserting the weft; the air feeding means also comprise at least one air feeding and accumulation system (31), suitable for allowing a pre-established quantity of air to be accumulated when the air is not flowing to the nozzles (14-17) and suitable for regulating the air flow-rate when it is flowing to the nozzles (14-17).
摘要:
A device for weaving the trimmings (23) of a fabric (24) produced by means of shuttleless weaving machines, comprising a device (1) with at least one satellite epicycloid gearing (13), each of which has at least one eyelet (8), situated in an eccentric position with respect to the axis (6) of the relative satellite (13), following an elliptic path; the weaving threads (4, 4A), passing through said eyelets (8), come from packs (2) of yarn arranged on a support (9) outside the device (1), which can rotate in synchrony with the gearing (11), so as not to intertwine the threads (4, 4A) with each other in the feeding tract, or can remain fixed, when the gearing (11) is rotated, alternately, in two opposite directions, so as to maintain the twist exerted or removed from the threads (4, 4A) on an average null.
摘要:
A control device for textile weaving looms (23), which enables the simple and efficient connection of the axle (18) of the driving motor (1) with the main axle (3) and various secondary axles (6,26) to carry out all the typical operations of a loom; the loom control device (23) provides at least one gear (2) rigidly connected to the driving axle (18) of the control motor (1), which controls the main axle (3) and the secondary axles (6,26) through further gears (4,5). The main axle (3) supplies movement to the comb or sley (23A) of the loom (23) and to all the auxiliary groups connected to it while a second secondary axle (6) supplies movement to the accessory and shed formation devices (22).
摘要:
A modular drive system (18) for weaving machines, adapted to realise an individual actuation of each mechanism belonging to a set of mechanisms which intervene in the weft insertion cycle and, consequently, in the formation of the fabric, with variable mutual phasing between one actuation and the other, according to the technological weaving needs, and possibility of individual variation of the motion diagram of each servo-mechanism; the drive system (18) comprises a series of control devices, each of which is composed of two parts, of which one operates individually on the assigned drive device, while the second part is integrated inside one common base (19) with the other control devices, regarding the shareable functions of the machine, which can be the system of power supply, communication, management and control, energy recovery or electrical flywheel, and braking for safely stopping the machine, etc.

摘要:
An angular servo-motor for the controlled positioning of elements connected to weft or warp yarns, in a weaving machine, essentially comprising a position control angular motor, with direct current sent to a "brushless" rotor (1), the latter connected to a sequence of elements consisting of cables (5) and small heddle-carrier looms (10, 11); the servo-motor in question is capable of conferring an alternating motion to the aforesaid small heddle-carrier looms (10, 11), such to obtain the desired weaves between the weft and warp yarns.
