Conveyor for sewing machines for closing the tip of hoses

A conveyor for sewing machines for closing the tip of hoses, comprising a pair of substantially co-planar flat strips which are laterally adjacent to each other and have, on their mutually facing sides, a pair of protruding ridges which laterally delimit a passage for a portion of the hose, proximate to the tip, which is knitted with a reduced thickness with respect to the contiguous regions;

• each one of said ridges having, along the advancement direction of the hose along said passage, an initial portion and a final portion which are substantially parallel, are mutually spaced and are joined by an inclined intermediate portion, means for advancing the hose along said passage being provided above said flat strips at said passage;
• the conveyor further comprising, arranged above each one of said ridges, starting from a region of said initial portion, a lamina which forms a resting surface for the upper border of said thinner portion of the hose, and supporting means for supporting each said lamina in the conveyor such that each said lamina is adjustably movable with respect to the corresponding ridge towards or away from the corresponding ridge such that the position of each said lamina with respect to the corresponding ridge is adjustable, and the conveyor further comprising adjustment means acting on said supporting means for automatically adjusting the position of each said lamina with respect to the corresponding ridge.
