Abstract: A plate sleeve-holder cylinder provided with a carbon-fibre central tube (T) comprising compressed air channels (6, 7, 8) arranged between one of the end flanges (Fb, Fm) of said plate sleeve-holder cylinder and a plurality of holes (H) formed in the outer surface of said central tube (T) made of carbon-fibre composite material. Said air channels (6, 7, 8) are partly embedded within said end flanges (Fb, Fm), partly within a thickness of a side wall (P) of said central tube (T) made of carbon-fibre composite material. Additionally, a process of manufacturing said central tube (t) is disclosed by inserting air pipes (6) into grooves (1) which are formed by mechanical milling of a surface of the supporting structure (P) of said central tube (T) obtained through a first lamination and polymerization, said grooves being coated with a surface finishing structure (S) obtained through a second lamination and polymerization.

Abstract: A heald supporting frame constituted by a pair of horizontal cross-members for supporting the healds which are mutually rigidly locked by removable side members. The cross-members of the frame are formed by box-like structures made of composite material, in the ends of which inserts with high mechanical strength, made of metallic or composite material, are embedded so as to couple them, and the side members, as well as bushes for connecting the frame to the loom, are mechanically fixed to the inserts.

Abstract: The separator structure for guiding weaving loom frames comprises a pair of spaced-apart parallel plate-like elements joined to one another by at least one separate side member which extends along a portion of the periphery of the plate-like elements. Coupling formations are furthermore provided to stably join the plate-like elements and the side member. The coupling formations are defined by channels formed on the inner faces of the plate-like elements and by protrusions formed on the edges of the side member. The protrusions are complementarily shaped to the channels and engage therein. The separator structure is placed astride a weaving loom for guiding and preventing the weaving loom from bending during vertical movement thereof.
