Abstract
Abstract An arrangement of movable thread-contacting lamellae for use on a wave-type loom, said arrangement comprising a plurality of thread-contacting lamellae that are guided during movements therefore in open zones between plate-like guide elements, disposed side-by-side in a row over the width of the loom, said elements being assembled together to form a unitary pack, and means for directing streams of air through the zones between the guide elements in which movements of the thread-contacting lamellae occur whereby accumulation of textile fibers, produced during the operation of the loom, within said zones is prevented.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
In a movable thread-contacting lamellae arrangement for use on a wave-type loom for weaving of textile material, wherein a first plurality of thread-contacting lamellae for effecting beat up of the weft threads and a second plurality of threadcontacting lamellae forming heddles for positioning the warp threads so as to produce sheds thereof are respectively guided during their movements in open zones between respective unitary packs of plate-like guide elements with the guide elements of each pack disposed side-by-side in a row widthwise of the loom, the improvement which comprises: air discharge means defining first and second elongated air discharging chambers arranged within the interior of the arrangement, each said chamber having a unitary air discharge opening extending lengthwise of one of the packs of guide elements and being in open communication therewith, and air passage means for supplying air to said chambers in order to provide for directing streams of cleaning air through at least the zones between the guide elements in which movements of the thread-contacting lamellae occur, whereby accumulation of textile fibers produced during the operation of the loom within said zones is prevented.
Claim 2
Dependent Claim
186 words
In a movable thread-contacting lamellae arrangement for use on a wave-type loom for weaving of textile material, wherein a first plurality of thread-contacting lamellae for effecting beat up of the weft threads and a second plurality of threadcontacting lamellae forming heddles for positioning the warp threads so as to produce sheds thereof are respectively guided during their movements in open zones between respective unitary packs of plate-like guide elements with the guide elements of each pack disposed side-by-side in a row widthwise of the loom, the improvement which comprises: air discharge means defining first and second elongated air discharging chambers arranged within the interior of the arrangement, each said chamber having a unitary air discharge opening extending lengthwise of one of the packs of guide elements and being in open communication therewith, and air passage means for supplying air to said chambers in order to provide for directing streams of cleaning air through at least the zones between the guide elements in which movements of the thread-contacting lamellae occur, whereby accumulation of textile fibers produced during the operation of the loom within said zones is prevented.
Claim 3
Dependent Claim
73 words
The arrangement of claim 1 in which said air-discharging chambers extend in the longitudinal direction of said packs of guide elements, said chambers each being defined by at least one limiting surface, being contiguous with their respective packs of guide elements, and opening toward the zones between said elements; said air passage means comprising a plurality of air passages which terminate in said chambers; and an air supply means connected to said passages.
Claim 4
Dependent Claim
87 words
The arrangement of claim 2 in which said first plurality of thread-contacting lamellae are lamellar reed teeth that are disposed between their guide elements and that project at one of their ends from the guide elements through the warp threads, the arrangement further including a driving means extending in the longitudinal direction of said packs of guide elements, said reed teeth being driven to perform swinging movements by said driving means and at least one of said limiting surfaces comprising a lateral face of the driving means.
Claim 5
Dependent Claim
29 words
The arrangement of claim 3 in which one of said elongated air discharging chambers is in the form of an elongated cavity which is contiguous with the driving means.
Claim 6
Dependent Claim
54 words
The arrangement of claim 3 in which said reed teeth are disposed to be swung about a horizontal plane and one of said air-discharging chambers is located above the reed teeth and extends towards a side of one of the packs of guide elements generally opposite the side from which the reed teeth project.
Claim 7
Dependent Claim
44 words
The arrangement of claim 2 in which the guide elements of at least one of said packs are held by a support which extends in the longitudinal direction of such pack, and one of said limiting surfaces comprises a side face of the support.
Claim 8
Dependent Claim
36 words
The arrangement of claim 2 in which the said air passages are formed by longitudinal slots, said slots being spaced at regular intervals from each other in the longitudinal direction of the packs of guide elements.
Claim 9
Dependent Claim
60 words
The arrangement of claim 2 in which the guide elements are plate-like in form and a portion of at least one of said packs of guide elements is provided with a covering layer extending over the length of such pack for directing cleaning air into the zones between the guide elements of such pack where said reed teeth are moved.
Claim 10
Dependent Claim
53 words
The arrangement of claim 8 in which one of said elongated air-discharging chambers is open in a direction extending towards the textile material being woven, and the portion of said one of said packs of guide elements covered by the covering layer is located between such elongated air-discharging chamber and the textile material.
Claim 11
Dependent Claim
39 words
The arrangement of claim 2 in which said air supply means comprises a suction fan provided on the loom, the exhaust of said fan being passed via air delivery means through the air passages into said elongated air-discharging chambers.
Claim 12
Dependent Claim
63 words
The arrangement of claim 1 in which one of said air-discharging chambers is provided on one of said packs of guide elements adjacent to the textile material formed on said loom, said chamber being in open communication with said open zones and extending the length of such pack, and an air supply means for directing air uniformly along the length of said chamber.
