Abstract:
The complete assembly which comprises the body of the cam casing, the connection between the casing and the batten, the bearing which supports the pivotal shaft of the lever which carries the toothed sector as well as its connection with said casing and with the batten is constructed in the form of a onepiece unit, that is to say a single part.
Abstract:
The arrangement according to the invention consists in the provision, over at least one part of the length of one of the strips of which the tape consists, of perforations corresponding to the dimensions and to the pitch of the teeth of the wheel on the engaging radius of the said strip, while the corresponding perforations of the other band or bands are given an additional length of a magnitude and direction corresponding to the difference in length between the engaging arc, based on the middle fiber, by which engagement is made with the strip or strips having enlarged perforations, on the one hand, and that by which engagement is made with those having normal perforations, on the other hand, this arrangement being applicable in the converse manner to the respective strips in other parts of the tape.
Abstract:
A loom with weft feed by means of bobbins located outside the shed and comprising at least one weft-inserter at one extremity of a flexible tape formed by at least two strips as well as an upper guide and a lower guide for guiding the tape along its path outside the shed and a toothed rotary system engaged with perforations of the tape in order to impart a reciprocating movement to said tape, wherein at least the strip or strips of the tape other than the inner strip are engaged with the toothed rotary system solely in the zones of the upper and lower guides so that each of said strips forms a floating loop between the outer extremities of said guides at a distance from said toothed rotary system, the successive strips being engaged over the teeth of the rotary drive system in such manner as to ensure that the perforations formed in the loops of successive strips as considered from the interior towards the exterior should increase in number between two teeth which are located respectively in said two zones.
Abstract:
Weaving machine with weft supply by spools located outside the shed, comprising at least an inserter, or weft picker, having a flexible strip with perforations for its drive engagement by meshing with a toothed driving wheel designed to be driven along an alternating rotation movement, characterized by the fact that it comprises at least one auxiliary idle wheel comprising on the one hand means to bear on the face of the strip remote from the drive wheel axis, in the cooperation zone between the strip and the drive wheel, to prevent the strip being separated from the driving wheel axis and on the other hand, meshing means provided on its circumference and so adapted that, in said cooperation zone, a rotation movement is imparted to it by that of the drive wheel.
