Processing of edgings
1. How can I edge boards properly, when out of the workshop?
With mobile glueing machines e.g. the Wegoma-Set boards can be edged properly and easily on site. Alternatively, if you don’t have a machine you can use T-bar edgings from Ostermann. All ABS edgings from 2mm can be retro fitted with a T-bar. It works like this: route a 3.5mmwide groove in the board, apply Kantol edging glue to the T-bar, knock the T-bar into the groove, then after an hour mill the edging flush. Finished. For use on sloping surfaces and projections the T-bar can be offset to the left or right.
Special tip: For special requirements e.g. in the kitchen, laboratory or bathroom PUR – adhesive can be processed with mobile glueing machines. After this work stir in a half to a full handful of blue PUR cleaning granules in the hot melt adhesive basin and run about half a meter of leftover edging through it until the PUR-/cleaner mixture is on the roller. Then the hardened mixture can be re-heated and removed the next day.
2. ABS edgings with real aluminium surfaces or solid aluminium - What is the difference?
Ostermann has various aluminium edgings in its range. ABS edgings with real aluminium surfaces are easier to process, as with other ABS edgings. In addition solid aluminium edgings are available to carpenters/cabinet makers on rolls or in straight lengths .These are of course somewhat more challenging to process. PUR adhesive should be applied to solid aluminium edgings. Before the application heat the whole of the edging in a heat press or another heat source to about 45-50 degrees C, so that the adhesive doesn’t bond too quickly. A very thin application of Teflon oil on both sides of the edging which has to be trimmed makes trimming considerably easier. Notice: do not get Teflon on the bonding side.
Special tip: You can also heat the tape holder for the aluminium edging with a hot air device in order to keep the edging evenly tempered.
3. 1 or 2mm? Which edging is better?
That depends entirely . . . . With a 1mm edging you can have of course a considerably smaller radius. Then the edging is in line with the modern trend towards straight, clean lines and sleek furniture. The 2mm edging, also known as safety edging, is, as the name suggests, noticeably more stable and impact resistant. In fact even 3mm thick edgings are being used in the industrial manufacture of furniture – and for good reason.
Special tip: Ostermann experts still recommend the 2mm safety edging. The only exception is for modern sleek furniture with clean lines.
4. Which radii are possible with T-bar edgings?
ABS edgings with an added T-bar or double T-bar (groove milling 3.5 mm) can be processed with an outer radius of 30 mm. It is essential that in the range of the radius, the T-bar is cut up to the edging every 3 mm. Under equal conditions, an inner radius from 40 mm can be realised, as well.
The following radii can be realised with our T-bar edgings:
(with cut T-bar)
|T-bar edging Ideal||30 mm (20 mm)||30 mm|
|T-bar edging Kompakt||30 mm|
|T-bar edging Parat||20 mm||30 mm|
|T-bar edging Classic||40 mm||40 mm|
|T-bar edging (30 mm)||(40 mm)||60 mm|
|T-bar edging Elipse (25 mm)||(30 mm)||60 mm|
|T-bar edging Ergosoft||(30 mm)||40 mm|
|T-bar edging Standard||20 mm||20 mm|
|T-bar edging Tablo||(50 mm)||80 mm|
5. Processing of T-bar edgings
For outer radii, we recommend you to always hammer in the T-bar edgingswhile under tension. For inner radii, the edgings should be hammered in with pressure against the radius. Use a rubber hammer or a felt-coated tap-block.
