Double carpet tying automated device

FIELD: textile, paper.

SUBSTANCE: for this purpose device should be bound to the pistons with a progressive return movement. Tying device construction generally consists of two pairs of plates. The first pair passing between two carpet beaming discloses plates and waits the second. The second pair of plates, which carry a cut-off piece of carpet yarn, passes clutching two carpet beaming, through which the first pair have passed. Then the first pair picks carpet yarn ends, and when the piston moves back, it returns to its base position which yields a double carpet tying.

EFFECT: improved method.

SUBSTANCE: proposed winged gear partially dipped in oil bath is composed of cylindrical sleeve with inner helical groove. Gear with support ring and winged disc with semicircular grooves are fitted on opposite of said sleeve. Said support ring has radial oil intake channels, their lengthwise axes being located parallel with coordinate axes of support disc horizontal plane and shifted therefrom by e=(Di-dc)/2, where e is the shift of channels horizontal channels from coordinate axes, mm, Di is support sleeve inner diameter, dc is diameter or width of oil intake channel, mm. Oil discharge channels are made in top part of said sleeve. Winged disc has extra through lubing channels with their lengthwise axes located in horizontal plane and aligned with coordinate axes of semicircular grooves of winged disc. Note here that quantity of lubing channels equal the number of semicircular recesses while porous wicks are fitted in every lubing channel.

EFFECT: additional lubing of whorl surface rubbing against winged disc.

SUBSTANCE: machine for formation of composite materials by multidimensional weaving comprises guide template (60) with column guide elements (62) located in accordance with geometrical shape of pre-fabricated article, electrically-controlled mechanism (30) of three-dimensional movement, containing end to receive control signal used for receiving signal for controlling movement of corresponding geometry of pre-fabricated article, and output end (30A) to ensure three-dimensional movement, used for forming path according to signal for controlling movement of and spinning needle (14) connected with above outlet end (30A) and used for distribution of binding fibres between column guide elements (62) based on geometrical shape of pre-fabricated article. Proposed machine by means of column-type guide elements and electrically controlled mechanism three-dimensional motion provides possibility of movement of interwoven cords under action of weaving needle with their distribution between column guide elements along path to form guide template, applicable for large-size and complex multidimensional weaving and formation of composite material and providing effective high interlayer strength of composite material.

EFFECT: since for multidimensional weaving and formation of composite material fast formation technology is applied, technical process, executed by forming machine is automated.
