The object is to provide a slat for blinds which resists bending while satisfactorily retaining the rotatability of the slat. A slat (16) is formed with lifting/lowering cord insertion holes (16a) through which lifting/lowering cords are inserted, and b/a satisfies A where b is the slat-widthwise length of the lifting/lowering cord insertion hole (16a), a is the slat width, and e is the slat camber, and a projection (16g) is formed which projects beyond the general surface (16e) of the slat across an extension (16d) of the lifting/lowering cord insertion hole (16a) connecting the slat-widthwise end edge (16b) of the lifting/lowering cord insertion hole (16a) and the slat-widthwise end edge (16c) of the slat (16).

It is suggested in connection with the production of slat packages for Venetian blinds whose slats (3), placed over each other, are introduced between a first and a second transverse band (2, 2') in double rungs in carrying bands or ladders (1) consisting of bands or cords, and where the slats (3) are conveyed one by one tothe carrying band (1) and lifted after being introduced into a double rung (2, 2') - in order to enable mechanical introduction of the slats - that a double rung (2, 2') should be stretched between two teeth (4) projecting over the plane in which the slats are conveyed, that a slat (3) is conveyed forward until it has passed under the first of the two transverse bands (2, 2'), and that the slat (3) is then lifted so that when further conveyed it passes over the second of the two transverse bands (2, 2'). The slat (3) can be lifted by means of an inclined plane (5) placed between the teeth (4).

Une machine de production de jalousies comporte une station de perforation avec au moins deux groupes d'outils de perforation (14) afin de former des trous pour le cordon de relèvement dans au moins deux planchettes de jalousies successives dans la partie terminale libre d'une bande métallique (6) insérée dans la machine. La station de perforation est suivie d'une station combinée de montage et de séparation, ladite station de séparation comportant au moins un nombre correspondant de poinçons de séparation (17) pour séparer simultanément les planchettes de jalousies pour le même nombre de jalousies produites simultanément. La présente invention est basée sur le fait que l'avance de la bande métallique (6) le long du banc de la machine (2) doit se produire pour des laps de temps continus et maximum avec un minimum de cycles d'accélération et de retard pendant la production des jalousies.

A stringtape roll for Venetian blinds, where the arresting member for the stringtape of the Venetian blind is constituted by a flexible tongue (7) which is bendably connected to the stringtape roll (1) and intended to be bent to locking engagement against the stringtape roll and thereby to lock the stringtapes which are arranged about this. The tongue (7) and the stringtape roll (1) have locking means corresponding to each other (9, 10) for locking the tongue in locking position against the stringtape roll. The invention furthermore refers to a stringtape jig for locking the tongue (7) to the stringtape roll (1) with the stringtapes in correct position.

An apparatus for manufacturing cellular laminate structural panels includes one or more supply stations (62) of a flexible strip material (96) including folding rollers (66) for sequentially folding the strip material into cellular structures and feeding the cellular structures into a conveyor where the cellular structures are held in compression. The apparatus further includes a laminating station (68) where the folded cellular structures are laminated to an upper and/or lower sheet material to which lines of a bonding medium (74) have been applied prior to engagement with the cellular structures. The folded cellular structures are heated (176) before engaging the sheet material so as to enhance the bonding of the sheet material to the cellular structures and subsequent to bonding, the laminate is passed through a cooling station (227) to set the bonding medium. Downstream from the laminating station, the laminate passes through a side edge folding station (80) where edges of the sheet material are folded over side edges of the laminate to finish the side edges of the laminate and subsequently the laminate is passed into a cutter (82) for cutting the continuous laminate into predetermined lengths. Ends of the cut panels then receive rigid edge strips (86) to fully finish the panel. The method of the invention includes the steps performed by the components of the apparatus.

An apparatus (10) is provided for automatically cutting stripematerials (22) into slats (20) for a venetian blind. The apparatus (10) has a feeding station (12), a cutting station (14), a punching station (16) and a laddering station (18). Strip materials (22) for the slats (20) are stored in a magazine (24) of the station (12) and they are fed one at a time to the cutting station (14) for cutting into slats (20) of preset length after slots (46) have been punched. The slats (20) are then fed to the laddering station (18) for assembling into blinds. A sensor (56, 58) is positioned to sense remnants of the strip material (22) and the remnants are automatically moved back to the feeding station (12) where they are lifted off the feeding path for ejection by a following strip (12).
摘要:
A mini-blind cutter for selective manual in-store sizing of a first mini-blind product having a vinyl headrail and bottom rail and a second mini-blind product having a steel headrail and bottom rail. The mini-blind cutter includes a die assembly movable from a first position to a second position having a first and second region to receive the first and second mini-blind products. The handle operation preferably rotates in a horizontal plane, the die assembly is adapted to cut different shape product in its two positions and the cutter sequences movement of the die assembly to reduce the force required to cut several components of a mini-blind in a sizing operation.
