Class 89 (ii) Staples are bent up from wire or strip with a central leg 13 of double thickness. The end legs 12, are left sufficiently sharp by the cutting of the wire but the leg 13 may be sharpened during making.

The nails or staples are connected in lengths by adhesive for use in nailing-machines.
