DEVICE FOR CUTTING-OUT CARDBOARD BLANKS Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: this device is intended for cutting-out blanks of sheet or sheets of cardboard and it has upper cutting-out frame 12 and lower cutting-out frame 14. In operation, upper cutting-out frame performs vertical reciprocating motions relative to lower cutting-out frame, thus cutting out blanks B1-B8 from cardboard sheet S located between aforesaid frames. Installed on lower frame are cutting members W1-W6 which are cutting sheet. Installed on upper frame are profile strips P1-P8, that is one strip per single blank being cut out. Configuration of each shape strip generally corresponds to shape of blank. Position of all these strips can be adjusted with respect to lower cutting-out frame so that blanks of any required configuration can be cut out from cardboard sheet S located between cutting-out frames. Installed on upper cutting-out frame 12 are movable lateral members 20, 22, 24, 26 which can be adjusted in position relative to lower cutting-out frame 14. Profile strips P1-P8 can be adjusted in position on lateral members. Aforesaid embodiment of device allows for simplification of design and ensures simple and reliable setting of profile strips. EFFECT: higher efficiency. 1 cl, 3 dwg
