The embodiments of the invention in which an exclusive property or privilege is claimed in connection with articulations of this invention for its application in textiles field are specifically defined as follows:

1. It is prominently claimed that because the cutter is directly mounted on the moving sley, which is having oscillation motion on a circular arc path, and the weft cutter is so specifically positioned, that it rises to meet the weft thread at the time of cutting when sley is at the backward most position and gets lowered during subsequent beat up operation, so as to clear the path for the reed to complete the beating up of inserted weft till the fell of the cloth, which completely removes interference of the weft cutter and the reed during beat up operation, which eliminates need for cutting of reeds (or limitations on actual length of the reed) as per width of the fabric woven on the machine and this is claimed to be major and one of the most significant achievements of this invention, which had not even been thought about hereinbefore.

2. It is further claimed that the weft cutter is mounted on sley which swivels around shaft (1) to which brackets (2) attached to which are the Brackets for mounting Reed holder (3), a long tee slot arrangement (4) having length between 150 to 750 mm and having a tee slot suitable for bolts from metric specifications M6 to M12 is attached to Brackets (2) in such a manner that the tee slot runs across the width of the weaving machine and swivels along with the brackets (2), an adjustable part (5) sits on the tee slot part (4) such that it can be adjusted at desired position in tee slot widthwise by means of two fasteners at places (6 & 7) and secured to the tee slot in set position while operation. Scissor blade arrangement (8) fits in the top portion of part (5) in such a manner that the scissors opening projects towards the top to receive the weft to be cut automatically as colour selector finger (9) is lowered for weft pick-up by gripper head.

3. It is sequentially claimed that the tee slot part (4) has two brackets (10 & 11) at its two extreme ends fitted to the tee slot part (4) in such a way that a long but thin shaft of diameter 8 to 15 mm (12) runs through them and through the part (5) in such a manner that the shaft slides freely in all of these three guides formed by parts (5, 10 & 11). Part 13 is fixed securely to the Shaft by means of a slot and screw clamping arrangement on part (13) itself, in such a manner that it can be set at desired position widthwise on the shaft relative to the Part (5). A spring (14) having length between 10 to 50 mm sits on shaft (12) in such a manner that it gets in between part (5) and part (13) so as to create return arrangement for shaft (12), after it is pushed forward and same function is repeated for another similar spring (15) at the extreme end of rod (12) but this remains fixed by a simple collar in place of part (13) and no setting is required here as nothing moves on changing position of part (5) for fabric width setting.

4. More over it is claimed that the link (16) which has a length between 30 to 150 mm is fitted on a projection on part (13) and to one end of scissor blade (8) in such a manner that when shaft is pushed to the right (or forward), the lever actuates the scissor blade to cutting of weft thread as plate (17) is secured on part (5) and one end of this plate has an attachment to arrests the free end of scissor blades so that the movement of this side of scissor blade is blocked, thus bringing in cutting action of the weft thread which has fallen in the scissors.

5. It is thus claimed that a shaft (18) having diameter between 10 and 20 mm, driven axially forward and backward by means of surface Cam (19) mounted on machine frame/body and has a projection "?" on its surface for displacing roller follower in its angular movement over cam surface and it is specifically claimed that disc surface cam (19) is adjustable in angular position by means of slots in machine body / frame (21) and secured after setting by plate (20) mounted above this arrangement from other side of body/frame (21) and further to it an eccentric cam (22), which is having eccentricity between 10 to 50 mm, and is mounted on a shaft running equal to rotational speed of machine, which is again, equal to weaving cycles.

6. It is further claimed that the cam (22) drives the Shaft (18) through arrangement of link (13), special drive sleeve (24) having keyway connection, in such a manner that the shaft (18) is free to move forward and backward along its axis without disengaging the axial drive input by of special drive sleeve (24) and another strong spring numbered (25) Presses the shaft on to the surface cam (19), bearing and follower (26) is securely mounted on shaft (18) is arranged as shown in diagram, shaft (18) comes in front of the shaft (12) described above at backward most position of the sley, and this is the exactly position at which the weft cutting is required which is again co-incident to a position, where gripper had just moved forward and taken the weft thread and the other end of weft thread catched and carried by the selvedge forming device is to be cut so that the picked weft is carried through.

7. Further to above claim, it is subsequently claimed that these shafts (18 & 12) have a clearance of 0.5 to 5 mm, tip to tip, in front of each other, to allow shaft (12) to move freely to come in front of the shaft (18) and then move away from in front of shaft (18), and further when the cam (19) imparts forward thrust to shaft (18), it gets transferred to shaft (12) and through link and scissor arrangement as described in Diagram 1 above the weft is cut at precise timing set by angular position of surface cam (19) relative to machine body /frame (21).

8. It is subsequently claimed that at the backward most position of sley, the weft cutter blades (8) swing in to cutting position by virtue of its placement on the beat up mechanism or sley. When the beat up operation is done the cutter blade escapes below the temple and adjacent assemblies just like the rapier guides. At the backward most position shaft weft cutter actuation shaft (12) and cam driven push rod (18) coming from the cam spring and follower assembly are in the same axis separated by a clearance of 0.5 to 5 mm, and at this time the roller follower (26) is riding on the projection "?" on the surface cam and further when the follower bearing escapes the projection "?" on surface cam, the spring (25) is decompressed and imparts rapid axial thrust to shaft (18), as the roller escapes the projection "P", this motion gets transferred on shaft (12) which is in the same axis at this time of weaving cycle and this activates link (16) through part (13) fitted on shaft (12) resulting in snap type cutting action at the right moment set by the angular position cam (19) around its mounting axis.

9. It is claimed in furtherance that when the cam (22) takes back the follower in its return stroke, roller follower rides back on projection "?" on surface cam, shaft (18) gets retracted back compressing the spring (25) again, thus shaft (12) also returns back to its rest position as springs () push it back to normal and a clearance gap of 0.5 to 5 mm is opened again between tip to tip between shaft (12) & shaft (18) thus opening the scissor blades and remain in that position until the sley completes beat up cycle all over and comes back in backward most position for next pick and new weft thread is picked up by the gripper and scissors are back in cutting timing position.

10. It is finally and typically claimed that setting of cutter position for a given weaving width of a fabric is done by loosening fasteners at places (6), (7) & fastener for part (13), the machine is manually turned until a point that a colour selector presenter comes down, gripper picks the weft thread, and at this point, fasteners (6) and (7) only are fastened, part (13) is clamped next on shaft (12) with weft cutter scissors kept open, further fasteners clamping part (20) on to the machine body are loosened, the machine is turned back through a few degrees and turned forward again until a moment when the cutting of weft is desired, manually through diametrical holes on the part (20) is turned, the cam (19) also turns along with it, this is done until the follower (26) falls off projection "?" on the cam, and this is the moment when shaft (18) thrusts shaft (12) for cutting action, and part (20) is clamped to body at this moment, this completes setting procedure which can even done by a layman as it is simple enough.

It is thus claimed in continuation that this is novel weft cutter is an omnipotent device and can be applied and used for all types of rapier weaving machines and capable to be articulated for use on flexible rapiers, rigid rapiers and telescopic rapier weaving machines as alternative embodiments of this invention .
