Patent

CA 2729026

A length of rigid linear stock building mate.pi.al bearing along its exterior surface regular indicia of longitudinal distance from a reference point also on its exterior surface, such that an installer need only measure the length of t he pipe run needed and may then immediately locate that position and cut the pipe to be installed to the desired length without the need to use a measuring device to transfer the desired length to the pipe before cutting. An apparatus for marking indicia of length and cutting extruded pipe including means for cutting the pipe, means for sensing the speed and position of the pipe, and means for marking on the pipe. A similar method and apparatus for manufacturing and/or marking non- extruded linear building materials is also disclosed.

La présente invention concerne une longueur de matériau de construction de stock linéaire rigide comportant, sur sa surface extérieure, des indications régulières de distance longitudinale depuis un point de référence également situé sur sa surface extérieure. Ainsi, un installateur n'a besoin de mesurer que la longueur du tuyau nécessaire ; il peut alors immédiatement localiser cette position et couper le tuyau à installer à la longueur souhaitée sans devoir utiliser de dispositif de mesure pour transférer la longueur souhaitée du tuyau avant de le couper. L'invention porte également sur un appareil permettant de marquer des indications de longueur et de couper un tuyau extrudé, comprenant des moyens de découpe du tuyau, des moyens de détection de la vitesse et de la position du tuyau, et des moyens de marquage sur le tuyau. L'invention concerne en outre un procédé analogue et un appareil permettant de fabriquer et/ou de marquer des matériaux de construction linéaires non-extrudés.
