Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 189 words
An inserting carrier for looms with removal of the filling yarn from stationary bobbins, said filling yarn being presented in the carrier in a vertical plane essentially, said carrier having a filling yarn clamping device and a warp divider piece attached to the top of the rear side wall of the carrier facing away from the point of formation of the shed, the upper edge of said divider piece being developed as an ascending first yarn guide curve and passing into an open yarn groove which is covered by a horn which protrudes in a direction away from the point of formation of the shed, characterized by the fact that the filling yarn clamping device is formed from a spring-loaded clamping tongue which is swingable perpendicularly to the central plane of the warp yarn and supported on the bottom surface of the carrier; a second yarn guide curve extending from the rear side wall of the carrier towards the front side wall is connected to the first yarn guide curve; and a third yarn guide curve leads from the horn up to the clamping slot of the clamping tongue.
Claim 2
Dependent Claim 189 words
An inserting carrier for looms with removal of the filling yarn from stationary bobbins, said filling yarn being presented in the carrier in a vertical plane essentially, said carrier having a filling yarn clamping device and a warp divider piece attached to the top of the rear side wall of the carrier facing away from the point of formation of the shed, the upper edge of said divider piece being developed as an ascending first yarn guide curve and passing into an open yarn groove which is covered by a horn which protrudes in a direction away from the point of formation of the shed, characterized by the fact that the filling yarn clamping device is formed from a spring-loaded clamping tongue which is swingable perpendicularly to the central plane of the warp yarn and supported on the bottom surface of the carrier; a second yarn guide curve extending from the rear side wall of the carrier towards the front side wall is connected to the first yarn guide curve; and a third yarn guide curve leads from the horn up to the clamping slot of the clamping tongue.
Claim 3
Dependent Claim 40 words
The inserting carrier according to claim 1 in which the third yarn guide curve is formed by a top edge of a cover surface bearing the horn and by a stop edge of a front side wall of the carrier.
Claim 4
Dependent Claim 25 words
The inserting carrier according to claim 1 in which said yarn groove has a horizontally extending first portion and an obliquely downward descending second portion.
Claim 5
Dependent Claim 25 words
The inserting carrier according to claim 2 in which said yarn groove has a horizontally extending first portion and an obliquely downward descending second portion.
Claim 6
Dependent Claim 66 words
The inserting carrier according to claim 3 in which a plate-shaped deflection element extending perpendicularly from the rear side wall of the carrier into the inside of the carrier is fastened to the rear side wall at the height of the lower edge of the horizontal first portion of the yarn groove, and the top edge of said deflection element forms the second yarn guide curve.
Claim 7
Dependent Claim 29 words
The inserting carrier according to claim 5 in which the base, the two side walls, the bottom, and the cover surface of the carrier are formed as a unit.
