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.
