Guiding device for large-format manual cutters

A guiding device for large-format manual cutters, comprising:

• an extruded aluminium guide (1), having a constant cross-section in the longitudinal direction and comprising:
• a top surface (11) comprising:
• an intermediate recessed portion (111) that covers the entire length of the guide and is delimited by a base (112) and by facing lateral surfaces which form longitudinal rails (113a, 113b) for movement of rolling means (32) of a manual cutter (3) provided with a cutting tool (31) arranged on one side of the guide (1);
• and two lateral portions (114, 115) located on either side of said intermediate portion (111);
• a bottom surface (12) which has on a first side (13) of the guide first vertical support means (121, 122) of the guide (1) on the part (P) to be cut and on a second side (14) of the guide a longitudinal recess (123) for receiving lever suction cups (2) which form second means for supporting and securing the guide (1) on the part (P) to be cut and
• hollow chambers (15) located between said top and bottom surfaces and separated by reinforcing ribs (151);
• so that the longitudinal rails (113a, 113b) for movement of the cutter are arranged between the first means (121, 122) and the lever suction cups (2), and the first support means (121, 122) are arranged between the cutting tool (31) and the lever suction cups (2) which form the second support means.
