Abstract
A unit for positioning a venetian blind ladder tape and for guiding the slats of a blind between individual rungs of a rung pair of a ladder tape, said unit comprising two body portions, a guiding member on each body portion, each guiding member locating, for movement longitudinally of the guiding member, one of the side tapes of the ladder tape and permitting the rungs to extend to the other side tape, the body portions being resiliently urged apart by a spring to tension the rungs. Each body portion carries a slat guide element which is positioned to feed slat material between the rungs of a pair and a resiliently retractable abutment plate is located adjacent each slat guide element, so as to engage the rung of a pair nearer thereto. The ladder tape is fed intermittently forward and is urged rearwardly between intermittent advances by spring-urged parts, so that the nearer rung of a pair is engaged against the abutment.
