Abstract
Abstract A weft end suction device for a jet-operated weaving machine having a weft-launching nozzle located at one side of the machine comprises a weft receiving and guiding block which is located in front of the weft-launching nozzle. The block has a suction opening for receiving the end of a weft thread launched from the opposite side of the machine, and a launching passage extending through the block. The block is reciprocatable between a position in which such launching passage is aligned with the weftlaunching nozzle, to transmit a weft thread launched from the nozzle, and another position in which the suction opening is aligned with the path of a weft thread launched from the opposite side of the machine.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
121 words
A weft end suction device for a jet-operated weaving machine having a weft-launching nozzle located at one side of the machine, comprising a weft receiving and guiding block which is located in front of the weft-launching nozzle and has a suction opening for receiving the end of a weft thread launched from the opposite side of the machine, wherein the improvement comprises a launching passage extending through the block, the block being reciprocatable between a position in which such launching passage is aligned with the weft-launching nozzle, to transmit a weft thread launched from the nozzle, and another position in which the suction opening is aligned with the path of a weft thread launched from the opposite side of the machine.
Claim 2
Dependent Claim
121 words
A weft end suction device for a jet-operated weaving machine having a weft-launching nozzle located at one side of the machine, comprising a weft receiving and guiding block which is located in front of the weft-launching nozzle and has a suction opening for receiving the end of a weft thread launched from the opposite side of the machine, wherein the improvement comprises a launching passage extending through the block, the block being reciprocatable between a position in which such launching passage is aligned with the weft-launching nozzle, to transmit a weft thread launched from the nozzle, and another position in which the suction opening is aligned with the path of a weft thread launched from the opposite side of the machine.
Claim 3
Dependent Claim
33 words
A weft end suction device according to claim 1 wherein the weft receiving and guiding block is vertically reciprocatable and in its uppermost position has its launching passage aligned with the weft-launching nozzle.
Claim 4
Dependent Claim
84 words
A weft end suction device according to claim 1 wherein the reciprocatable block has a sliding engagement with a perforate side of a stationary suction header, has a suction passage leading from the suction opening to another opening located in the side of the block that is in sliding engagement with the header, and has two slots in the side of the block toward the header, one of which communicates with the suction passage and the other of which communicates with the launching passage.
Claim 5
Dependent Claim
70 words
A weft end suction device according to claim 3 wherein the edge of the stationary suction header adjacent to the block and to the cloth has a slot extending parallel to the warp which is aligned with the slot in the suction passage of the block when the suction opening of the block is aligned with the path of a weft thread launched from the opposite side of the machine.
Claim 6
Dependent Claim
40 words
A weft end suction device according to claim 4 wherein the stationary suction header is provided with a suction gap aligned with the slot in the edge of the header, and a thread-trimming device is arranged adjacent to such gap.
Claim 7
Dependent Claim
32 words
A weft end suction device according to claim 5 wherein a weft thread receiving and guiding piece of U-shaped cross section extends toward the cloth from the edges of the suction gap.
