<p>For each new width of profile, optimal cut starting points (A, B) are determined. These are located in relation to a reference point by the adjustable programmable control unit (28), and lie directly ahead of the profile (21) edges (30). Directly after the saw blade (24) has cut off a length of profile, the sawing unit is retracted and reversed. During retraction, the sawing unit is brought into the next optimal position to start a cut. An independent claim is included for corresponding equipment. It comprises in addition, a double conveyor belt to carry the continuous profile. The profile has a rigid foam core between covering layers. Retraction following cutting, is rapid. Preferred features: During location at the ideal point to start the cut, a safety spacing is added, clearing the edges of the profile. Saw blade (24) and a burr removal unit (26) behind it, are retracted sufficiently from the profile, that both can be used together.</p> |
