Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
92 words
A device for tensioning a warp (5) in a weaving machine, the device comprising a spring- biased rod-like tensioner element (9, 92, 9a) and a carrier beam (31) on which the tensioner element is borne at more than one place and around whose axis (81) the tensioner element can pivot, characterised in that the carrier beam (31), together with a warp-deflecting beam (8) disposed between the warp beam (6, 7) and the tensioner element (9, 92, 9a), is borne in a number of common bearing mountings (26) disposed within cloth width (B).
Claim 2
Independent Claim
92 words
A device for tensioning a warp (5) in a weaving machine, the device comprising a spring- biased rod-like tensioner element (9, 92, 9a) and a carrier beam (31) on which the tensioner element is borne at more than one place and around whose axis (81) the tensioner element can pivot, characterised in that the carrier beam (31), together with a warp-deflecting beam (8) disposed between the warp beam (6, 7) and the tensioner element (9, 92, 9a), is borne in a number of common bearing mountings (26) disposed within cloth width (B).
Claim 3
Dependent Claim
39 words
A device according to Claim 1, characterised in that the tensioner element (9) bears on the carrier beam (31) by way of at least one trough- shaped bearing (33) which extends in the direction of the carrier-beam axis (81).
Claim 4
Dependent Claim
27 words
A device according to Claim 1, characterised in that the tensioner element (9) is mounted for rotation relatively to the carrier beam (31) around the axis thereof.
Claim 5
Dependent Claim
59 words
A device according to Claim 1, characterised in that the carrier beam (31) is a rotatable hollow shaft receiving a torsion spring bar which comprises a number of component parts (45-47) and which is adapted to bias the warp (5), the component parts (45-47) being so interconnected by at least one coupling (52) as to corotate with one another.
Claim 6
Dependent Claim
29 words
A device according to Claim 1, characterised in that the tensioner element (9), carrier beam (31) and at least one web (92, 32) interconnecting them are a unitary member.
Claim 7
Dependent Claim
44 words
A device according to Claim 1, characterised in that the carrier beam (31) has a projection (32a) which extends over cloth width (B) and on which a strip (9a) is disposed, the same also extending over cloth width and being operative as tensioner element.
Claim 8
Dependent Claim
34 words
A device according to Claim 1, characterised in that the bearing mountings (26) are so connected to arms (25) as to be vertically adjustable, the arms (25) being secured to the machine frame (2).
Claim 9
Dependent Claim
75 words
A device according to Claim 1, characterised in that the connecting planes between, on the one hand, the axes of the deflecting beam (8) and carrier beam (31) and, on the other hand, of the carrier beam (31) and tensioner element (9, 92, 9a) include an angle which is at least a right angle, the warp yarns (5) being guided outside these connecting planes by way of the deflecting beam (8) and tensioner element (9).
