Abstract
Abstract A weaving machine of the type having at least at one side a weft inserting device and at the other side, carried by the reed, a catching means and a clamping means cooperating therewith, for receiving, catching and tensioning the weft threads launched through the weaving shed, has a guiding piece mounted on the reed which is adjustable in the weft direction and is provided with a receiving channel situated in the insertion path of the weft yarn, which channel deviates at its end remote from the weft inserting device into the beating up direction of the reed and is open towards the beating up side along its complete length, the catching means being positioned in front of the deviated receiving channel end and being movable from a receiving position, corresponding with the retracted reed position, in the weft direction relative to the clamping means which is also carried by the reed towards a clamping position corresponding with the beating up position of the reed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
187 words
A weaving machine of the type having at least at one side a weft inserting device and at the other side, carried by the reed, a catching means and a clamping means cooperating therewith, for receiving, catching and tensioning weft threads launched through a weaving shed, characterized by a guiding piece mounted to the reed adjustable in the weft direction and provided with a receiving channel situated in the insertion path of the weft thread, which channel deviates at its end remote from the weft inserting device into the beating up direction of the reed and has an opening on its beating up side extending along its complete length, the catching means being spaced in the beating up direction from the deviated end of the receiving channel, and being movably mounted on the reed for movement, generally parallel to the shed, from a weft thread-receiving position to a clamping position in which the weft thread is clamped between the catching means and the clamping means, and mechanism actuated by movement of the reed toward its beating up position for moving the catching means toward its clamping position.
Claim 2
Dependent Claim
187 words
A weaving machine of the type having at least at one side a weft inserting device and at the other side, carried by the reed, a catching means and a clamping means cooperating therewith, for receiving, catching and tensioning weft threads launched through a weaving shed, characterized by a guiding piece mounted to the reed adjustable in the weft direction and provided with a receiving channel situated in the insertion path of the weft thread, which channel deviates at its end remote from the weft inserting device into the beating up direction of the reed and has an opening on its beating up side extending along its complete length, the catching means being spaced in the beating up direction from the deviated end of the receiving channel, and being movably mounted on the reed for movement, generally parallel to the shed, from a weft thread-receiving position to a clamping position in which the weft thread is clamped between the catching means and the clamping means, and mechanism actuated by movement of the reed toward its beating up position for moving the catching means toward its clamping position.
Claim 3
Dependent Claim
53 words
A weaving machine according to claim 1, in which the weft inserting path is determined by a tunnel which is longitudinally open towards the beating up line and delimited by a plurality of substantially U-shaped reed blades, and wherein the guiding piece comprises a filling piece which is adjustably mounted in said tunnel.
Claim 4
Dependent Claim
90 words
A weaving machine according to claim 1 wherein said catching means comprises a catching eyelet having an escape aperture for the weft thread and a clamping surface cooperating with the clamping means, an ejection means being provided which is movable between a lower and an upper position, and having mechanism for moving the ejection means from its lower position to its upper position during movement of the catching means from its clamping position back to its receiving position, thereby ejecting the weft thread through the escape aperture of the eyelet.
Claim 5
Dependent Claim
64 words
A weaving machine according to claim 3, characterized in that the receiving eyelet is formed at the end of a lever which is pivotable around a shaft substantially extending in the warp direction, around which shaft also the clamping means constituted by a lever is pivotable from an abutting position into the weft direction together with the catching means brought into the clamping position.
Claim 6
Dependent Claim
112 words
A weaving machine according to claim 1 in which a cutting device for cutting the weft thread ends projecting beyond the relative cloth edge is provided at the side remote from the weft inserting device and wherein further a sucking nozzle is provided for sucking in the head ends of the inserted weft threads and subsequently sucking off the cut thread ends, characterized in that the sucking nozzle is provided with its sucking opening in the deviated portion of the path of the weft yarn, adjacent to the catching means and is adjustable in the transverse direction of the machine together with the guiding piece, the catching means and the clamping means.
Claim 7
Dependent Claim
125 words
A weaving machine according to claim 1 in which for inspecting the weft at the side remote from the weft inserting device a thread detection device is provided, said device substantially comprising a light source and a light sensitive resistance cooperating therewith, the light source being provided in a channel opening into a guiding channel for the weft thread, the light sensitive resistance communicating by a second channel with the thread guiding channel opposite to the opening of the light source channel, for receiving a quantity of light changing when a weft thread passes, characterized in that the thread detection device is provided such that the channels containing the light source and the light sensitive resistance open into the receiving channel in the guiding piece.
