Finger-Joint
Finger-jointing is used for the manufacturing for large glulam beams. In order to produce highly efficient glulam beams, graded lamellas of kiln dried timber go through the finger-jointing machine, where a finger profile of approximately 20 mm is machined in each end of the material. Then an appropriate structural adhesive is added and the finger joints of the laminates are moulded and glued together under pressure to form an "endless" board.
A major advantage of finger-jointing is that the length of a glulam beam is not limited by the size of a tree and it is possible to produce individual cross-sections with heights up to 3 m and lengths of up to 65 m.
