Abstract
A pendulum scroll saw including a lifting rod (1) for securing a saw blade (2), and a motor-driven entrain member (3) for reciprocating the lifting rod (1) with the lifting rod (1) having a guide surface (4) connectable with the entrain member (3), and with a contact region of the guide surface (4) with the entrain member (3) having a curved profile that deviates from a straight line.
Claims5
A pendulum scroll saw, comprising a lifting rod (1) for securing a saw blade (2);
- an entrain member (3) for reciprocating the lifting rod(1);
- and a motor (6) for pivoting the entrain member (3) about a rotational axis (R), the lifting rod (1) having a guide surface (4) connectable with the entrain member (3), with a contact region of the guide surface (4) with the entrain member (3) being formed by two curved profiles (4a, 4b) each deviating rigidly, monotonously from a straight line.
