Abstract
Abstract A shuttleless weaving machine, especially a ribbon loom, comprising at least one filling thread-insertion element and at least one to-and-fro driven knitting needle moving along the selvage or cloth edge which is situated opposite the filling thread-insertion element for the formation of a knitted edge by tying the inserted filling threads and/or auxiliary threads. There is further provided a deflection element operatively associated with the knitting needle for the introduction of filling threads or auxiliary threads, respectively, into the knitting region or zone of a hook of the knitting needle. The deflection element is driven so as to move back-and-forth and by means of an actuation element driven in cycle with the machine can be brought, transversely to its direction of movement, from a rest position into a knitting position where the deflection element deflects filling thread or auxiliary thread, respectively, to the knitting region of the knitting needle hook.

Claim 1
Independent Claim
196 words
A shuttleless weaving machine for weaving a fabric ribbon from weft threads and auxiliary threads, comprising at least one weft insertion element, at least one selvedge knitting needle having a hook, means for driving said selvedge knitting needle to-and-fro along a knitted selvedge edge of the fabric ribbon which is located opposite the weft insertion element for the formation of the knitted selvedge edge by knitting the inserted weft thread to the previously inserted weft thread or the auxiliary thread, a pivotable deflection element operatively associated with the selvedge knitting needle for controlled deflection of the weft thread or the weft thread and the auxiliary thread, into a knitting zone of the hook of the selvedge knitting needle, means for to-and-fro motion of the deflection element, an actuation element, means for driving the actuation element in cycle with the operation of said knitting needle and said deflection element so as to engage said deflection element for displacement thereof transversely with respect to the latter's direction of movement from a rest position into an operative position for acting on one of said threads or to deflect the latter into the knitting zone of the knitting needle hook.
Claim 2
Dependent Claim
196 words
A shuttleless weaving machine for weaving a fabric ribbon from weft threads and auxiliary threads, comprising at least one weft insertion element, at least one selvedge knitting needle having a hook, means for driving said selvedge knitting needle to-and-fro along a knitted selvedge edge of the fabric ribbon which is located opposite the weft insertion element for the formation of the knitted selvedge edge by knitting the inserted weft thread to the previously inserted weft thread or the auxiliary thread, a pivotable deflection element operatively associated with the selvedge knitting needle for controlled deflection of the weft thread or the weft thread and the auxiliary thread, into a knitting zone of the hook of the selvedge knitting needle, means for to-and-fro motion of the deflection element, an actuation element, means for driving the actuation element in cycle with the operation of said knitting needle and said deflection element so as to engage said deflection element for displacement thereof transversely with respect to the latter's direction of movement from a rest position into an operative position for acting on one of said threads or to deflect the latter into the knitting zone of the knitting needle hook.
Claim 3
Dependent Claim
41 words
The weaving machine as defined in claim 1 further comprising common support means for said knitting needle and said deflection element to be secured to, said driving means for said knitting needle including means for driving said common support means back-and-forth.
Claim 4
Dependent Claim
29 words
The weaving machine as defined in claim 1, wherein the actuation element comprises a lever driveable back-and-forth transversely with respect to the direction of movement of the deflection element.
Claim 5
Dependent Claim
32 words
The weaving machine as defined in claim 1, wherein the deflection element is formed of an elastically resilient material automatically springing into its rest position upon an applied force being withdrawn thereform.
Claim 6
Dependent Claim
21 words
The weaving machine as defined in claim 1, wherein the deflection element includes an eyelet for guidance of the auxiliary thread.
Claim 7
Dependent Claim
28 words

Claim 8
Dependent Claim
178 words
A shuttless weaving machine for weaving a fabric ribbon from weft threads and auxiliary threads comprising at least one weft insertion element, at least one selvedge knitting needle having a hook, means for driving said selvedge knitting needle to-and-fro along a knitted selvedge edge of the fabric ribbon which is located opposite the weft insertion element for the formation of the knitted selvedge edge by knitting the inserted weft thread to the previously inserted weft thread or the auxiliary thread, a pivotable deflection element operatively associated with the selvedge knitting needle for controlled deflection of the weft thread or the weft thread and the auxiliary thread into a knitting zone of the hook of the selvedge knitting needle, a displaceable deflection element, an actuation element, means for driving the actuation element for the latter to engage and displace the deflection element transversely with respect to the latter's direction of movement from a rest position into an operative position for acting on one of said threads to deflect the latter into the knitting zone of the knitting needle hook.
Claim 9
Dependent Claim
178 words
A shuttless weaving machine for weaving a fabric ribbon from weft threads and auxiliary threads comprising at least one weft insertion element, at least one selvedge knitting needle having a hook, means for driving said selvedge knitting needle to-and-fro along a knitted selvedge edge of the fabric ribbon which is located opposite the weft insertion element for the formation of the knitted selvedge edge by knitting the inserted weft thread to the previously inserted weft thread or the auxiliary thread, a pivotable deflection element operatively associated with the selvedge knitting needle for controlled deflection of the weft thread or the weft thread and the auxiliary thread into a knitting zone of the hook of the selvedge knitting needle, a displaceable deflection element, an actuation element, means for driving the actuation element for the latter to engage and displace the deflection element transversely with respect to the latter's direction of movement from a rest position into an operative position for acting on one of said threads to deflect the latter into the knitting zone of the knitting needle hook.
Claim 10
Dependent Claim
