Abstract The invention relates to a device for fixing test pieces made of bicomponent polymeric materials and maintaining them in horizontal position, in order to test their resistance to delamination. According to the invention, the device, mounted on a multi-purpose testing machine having a single mobile wedge grip, comprises a T system (2) with a mobile plate (3) for fixing one of the ends of the bicomponent test piece (4), a T system (5) with one plate (6) in which the other end of the test piece is fixed, the test piece being maintained in horizontal position between some rollers (8) which are rotatably supported in a case (9) that can slide, by means of a guide plate (10), on a guide (11) fixed at the end of a rack (12) movable inside a guide piece (13), an arm (14) linking the system (2) with a rack (15) which slides in a guide piece (16) and engages with a gear wheel (17) fixed on the same shaft (20) as the gear wheel (18). Invenţia se referă la un dispozitiv de fixare şi menţinere în poziţie orizontală a epruvetelor din materiale polimerice bicomponent pentru testarea rezistenţei la delaminare. Dispozitivul, conform invenţiei, montat pe o maşină de încercat universală, având un singur bac mobil, cuprinde un sistem T (2) cu o plăcuţă mobilă (3) pentru fixarea unuia dintre capetele epruvetei bicomponent (4), un sistem T (5) cu o plăcuţă (6) în care se fixează celălalt capăt al epruvetei, epruveta fiind menţinută într-o poziţie orizontală între nişte role (8) lăgăruite într-o casetă (9), care poate culisa, prin intermediul unei plăci de ghidare (10), pe un ghidaj (11) fixat pe capătul unei cremaliere (12) care se poate deplasa într-o piesă de ghidare (13), un braţ (14) solidarizând sistemul (2) cu o cremalieră (15) care culisează într-o piesă de ghidare (16) şi angrenează o roată dinţată (17) fixată pe acelaşi ax (20) cu roata dinţată (18).
