Abstract
Abstract A shield is provided upstream of the heating wire of the electrothermal fabric melt cutter to prevent cooling of the heating wire by a fanning action of the reed during beating-up. The shield extends to the fabric and may have a cover for further supporting the fabric during movement past the heating wire of the cutter.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
43 words
An electrothermal fabric melt cutter for a weaving machine comprising a heating wire having a severing portion for severing a moving fabric web; and a shield disposed about said heating wire to shield said severing portion of said wire from reed-induced air flows.
Claim 2
Dependent Claim
43 words
An electrothermal fabric melt cutter for a weaving machine comprising a heating wire having a severing portion for severing a moving fabric web; and a shield disposed about said heating wire to shield said severing portion of said wire from reed-induced air flows.
Claim 3
Dependent Claim
67 words
In a weaving machine having a reed for beating-up a weft yarn into a fabric and a fabric take-up roll, the combination of a heating wire between said reed and said roll having a severing portion for severing a fabric moving towards said roll; and a shield disposed between said heating wire and said reed to shield said severing portion of said wire from reed-induced air flows.
Claim 4
Dependent Claim
67 words
In a weaving machine having a reed for beating-up a weft yarn into a fabric and a fabric take-up roll, the combination of a heating wire between said reed and said roll having a severing portion for severing a fabric moving towards said roll; and a shield disposed between said heating wire and said reed to shield said severing portion of said wire from reed-induced air flows.
Claim 5
Dependent Claim
22 words
The combination as set forth in claim 2 wherein said shield is of U-shape with a pair of arms enveloping said wire.
Claim 6
Dependent Claim
19 words
The combination as set forth in claim 3 wherein said shield has a sloped forward wall connecting said arms.
Claim 7
Dependent Claim
26 words
The combination as set forth in claim 3 wherein said shield extends to the path of the fabric to said roll to support the fabric thereon.
Claim 8
Dependent Claim
39 words
The combination as set forth in claim 3 wherein said shield has a cover extending parallel and adjacent to the path of the fabric to said roll to support the fabric thereon with said wire projecting into said path.
Claim 9
Dependent Claim
25 words
The combination as set forth in claim 2 which further comprises an insulating block mounting said wire thereon with said shield secured to said block.
Claim 10
Dependent Claim
52 words
An electrothermal fabric melt cutter comprising a heating wire for severing a moving fabric in a weaving machine into separate webs; and a shield enveloping said wire with said wire projecting from said shield, said shield being disposed to protect said wire from air flows from a reed of the weaving machine.
Claim 11
Dependent Claim
52 words
An electrothermal fabric melt cutter comprising a heating wire for severing a moving fabric in a weaving machine into separate webs; and a shield enveloping said wire with said wire projecting from said shield, said shield being disposed to protect said wire from air flows from a reed of the weaving machine.
Claim 12
Dependent Claim
27 words
A cutter as set forth in claim 8 wherein said cutter includes an insulating block mounting said wire therein and means securing said shield to said block.
Claim 13
Dependent Claim
