Abstract
Abstract A weaving loom comprises a noise-absorbing cover (1) encasing the top side and, at least in part, the lateral sides of the shed-forming and weft-inserting devices and the reed. The noise-absorbing cover is equipped with control means (4) apt to shift said cover from a working position - wherein it is close to the warp yarns and to the fabric being woven - to a position granting access to the operator, wherein it is far from all the above-described fabric-weaving devices to allow the operator to have free access thereto. <IMAGE>

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
128 words
Weaving loom of the type comprising devices for forming the
shed among the warp yarns, devices for inserting the weft into the shed,
and an oscillating reed for beating the new wefts against the fabric
being woven, characterised in that it comprises a noise-absorbing cover
encasing the top side and, at least in part, the lateral sides of said
shed-forming and weft-inserting devices and the reed, and in that said
cover is provided with control means apt to shift said cover from a
working position - wherein it is close to the warp yarns and to the
fabric being woven - to a position allowing access to the operator,
wherein it is far from all the above-mentioned fabric-weaving devices to
allow the operator to have free access thereto.
Claim 2
Dependent Claim
53 words
Weaving loom as claimed in claim 1), wherein said control means
consist of two fluidodynamic cylinder-piston assemblies 4 positioned at
the two lateral ends of the noise-absorbing cover 1, the cylinder base
and the piston top of each cylinder-piston assembly being fixed to the
loom frame and to the noise-absorbing cover 1, respectively.
Claim 3
Dependent Claim
23 words
Weaving loom as claimed in claim 2), wherein said pistons are
fixed to the noise-absorbing cover in a barycentric position of the same.
Claim 4
Dependent Claim
31 words
Weaving loom as claimed in claim 2), wherein driving said
cylinder-piston assemblies into an operational or non-operational state
is automatically controlled according to the stationary or running
condition of the loom.
Claim 5
Dependent Claim
27 words
Weaving loom as claimed in claim 1), wherein said noise-absorbing
cover comprises an outer shell having a structural function,
and an inner lining having a noise-absorbing function.
Claim 6
Dependent Claim
31 words
Weaving loom as claimed in claim 4), wherein said outer shell
consists of a composite sandwich panel formed by two outer light-alloy
sheets, between which is inserted a noise-absorbing plastic core.
Claim 7
Dependent Claim
22 words
Weaving loom as claimed in claim 5), wherein said light alloy
is an aluminium alloy and said plastic material is black polyethylene.
Claim 8
Dependent Claim
24 words
Weaving loom as claimed in claim 4), wherein said inner lining
consists of foamed plastic plates having a thickness of at least 20 mm.
