<p>A tracing instrument (I) for cutting out a covering element (4c) to be fitted around the edges of an obstacle (II). The instrument consists of a combination of a template (300) capable of being fitted around the edges of the obstacle (II), a centring piece (200) comprising a cross member (230) designed to be engaged between the elements (1a, 1b, 1c, ..., 3c) of the positioned covering (III) so that the position of said instrument may be preset relative to a reference point on the covering (III), and a rule (100) interconnecting the template (300) and the centring piece (200) and maintaining the mutual spacing and relative positions thereof so that the instrument as a whole may be moved without altering the parameters. An original concept for a covering element tracing method using said instrument is also disclosed. Said method and instrument are useful for tracing covering elements prior to cutting.</p> |
