Description
00 ;Z1 00 TITLE: ROMAN BLIND BATITEN GUM~E FIELD OF THE INVENTION This invention concerns a method of making a Roman blind and apparatus for facilitating the manufacture of such blinds.
BACKGROUND OF THE YNVENTION Roman. blinds rely on the use of battens which extend from, selvedge to selvedge in the 00
O
O
.2blind fabric. Each batten has a series of eyes through which vertical control lines pass and these lines cause rise and fall in the blind. The battens are commonly aluminium extrusions and these attach to the fabric. One type of blind construction is described in our co-pending patent application no. 2006903061.
SThe extrusion in that specification had a pair of sidewalls which defined a fabric slot.
The assembled blind housed a 2-3mm diameter plastic rod which imprisoned a loop of Sfabric in the slot. End caps confined the rod and stabilised the structure. The extrusions C, are powdercoated and cut from stock lengths by a parting tool. This leaves the ends with sharp edges. During the assembly process the fabric is creased to create a loop of double thickness and the extrusion is slid across the fabric so that the crease enters the fabric slot. The sharp ends abrade the fabric and damage occurs unless the assembly is slow and careful. Consequently assembly is slow even with experienced assemblers.
SUMMARY OF THE INVENTION The method aspect of the invention provides a method of inserting a fold of fabric into the fabric slot of the batten of a Roman blind comprising, folding the fabric, seating a slotted guide on the leading end of the batten and offering the entrance of the slotted guide to the edge of the fabric fold and advancing the guide and batten together across the width of the fabric in order to progressively feed the fold into the fabric slot of the batten until the batten spans the width of the fabric.
Once the entire width of the fabric engages the batten, the guide is removed and used for a subsequent batten: End caps may be fitted on the ends of the batten once the guide is removed.
.Preferably a rod is placed at the site of the fold and both rod and fabric are offered to the entrance of the guide.
The advance of the guide imprisons the rod and fabric in the fabric slot of the batten.
When no rod is present the fabric may be retained in the fabric slot by subjecting the 00
O
O
4 -3extrusion to a crimping action to converge the sidewalls of the batten and nip the fabric.
When the assembly includes a rod, the procedure entails forming a fabric fold into a keyhole shape around the rod using a guide before it is presented to the leading end ofthe extrusion.
o The apparatus aspect of the invention provides a device for inserting a fold of fabric into the batten of a Roman blind comprising a sleeve with a leading end and a trailing end, a Sguide slot of substantially keyhole section extending axially from end to end.
Preferably the guide has means for aligning the slot with the fabric slot of a blind batten.
Preferably the leading end of the guide slot is chamfered or otherwise relieved to impose a keyhole conformation on the folded fabric.
Preferably the means for aligning the slot is a cavity in the trailing end of the sleeve and a spline or keyway projecting from the sleeve into the cavity. The spline or keyway may be adapted to engage with the batten. In a particular aspect the spline or keyway may be adapted to engage with a clip slot of the batten, which clip slot lies alongside the fabric slot. Engagement between the keyway and the clip slot ensures the guide slot registers with the fabric slot in the batten.
The sleeve may be machined from plastic rod or moulded. Likewise the device may be turned from timber dowel, die cast or machined from metal rod.
BRIEF DESCRIPTION OF THE DRAWINGS In the specification the fabric, extrusions, clips and lines are as described in our copending patent application no. 2006903061.
One embodiment of the invention is now described with reference to the accompanying drawings, in which: Figure 1 is an end view of the trailing end of the guide.

DETAILED DESCRIPTION WITH RESPECT TO THE DRAWINGS Referring now to Figures 1-4, the guide 2 is made from polyethylene rod 20mm in diameter and 30mm in length.
The trailing end 4 has a bore 6, 15mm deep and 11mm in diameter. The bore 6 is intended to receive the leading end of extrusion 8. A slot 10 runs axially from the trailing end 4 to the leading end 12. The slot has a T-section which, toward the leading end, opens into a countersunk central area 14 and the radial part 16 of the slot diverges. The sidewall of the bore 4 is drilled and threaded to support a screw 18 which projects into the clip slot 20 preventing rotation of the sleeve on the extrusion and ensuring that fabric slot 22 is always in register with the sleeve slot Referring now to Figure 5, prior to assembly the fabric is creased along fold lines perpendicular to the selvedge.
A 3mm polyethylene rod 24 a few millimetres longer than the fabric width is inserted 00
O
O
W between the looped Fabric 26.
One end of the extrusion 8 is offered up to the bore of the sleeve guide so that screw 18 enters the clip slot 20. The extrusion is pushed 15mm into the bore.
t¢ O The leading end of the guide 2 is offered up to the rod 24 so that the rod enters the countersunk area and then the slot. At the same time the fingers of the user's remaining 00 0 and pinch the fabric around the rod and feed the rod and fabric into a keyhole shape.
Once the entry has been made, the fabric can be held with one hand while the other hand pushes the extrusion together with the guide sleeve across the width of the fabric.
The sharp end edge of the extrusion never contacts the fabric. Once the extrusion spans the fabric, the guide sleeve is removed. The rod is now imprisoned in the fabric slot and cannot be pulled out of the extrusion. End caps (not shown) are pushed on and the blind is ready for the next batten.
We have found the advantages of the above embodiment to be: 1. Assembly time is reduced substantially.
2. Damage to the fabric is prevented.
Claims (2)
1. A device for inserting a fold of fabric into the batten of a Roman blind comprising, a sleeve with a leading end and a trailing end, and a guide slot of Ssubstantially keyhole section extending axially from end to end. O 2. The device according to Claim 1 comprising means for aligning the guide slot _with a fabric receiving slot of the batten. 00 S3. The device according to any one of the preceding claims wherein the leading end 0of the guide slot is chamfered or otherwise relieved to impose a keyhole conformation on the folded fabric.
4. A device substantially as hereinbefore described with reference to the accompanyng drawings. A method of inserting a fold of fabric into the fabric slot of the batten of a Roman blind comprising, folding the fabric, scating a slotted guide on the leading end of the batten, offering the entrance of the slotted guide to the edge of the fabric fold, and advancing the guide and batten together across the width of the fabric in order to progressively feed the fold into the fabric slot of the batten until the batten spans the width of the fabric.
