Abstract
The device for cutting sheet material length-wise includes a knife holder assembly which can be linked to a cutter bar. The knife holder assembly has a support body and a cutter head which carried a circular cutting knife and which can be adjusted vertically in relation to the support body. The knife holder assembly also has a connecting plug assembly for connecting the support body to the cutter head. The direction of connection extends in the plane of the circular cutting knife.
Claims3
A device for cutting material sheets lengthwise, comprising
- (a) a knife holder including
- (1) a support body;
- (2) an adjustment element movably guided in said support body and having a first bore;
- and
- (3) a cutter head having a second bore being in an end-to-end alignment with said first bore;
- said cutter head being a component separate from said adjustment element;
- (b) means for mounting said support body on a cutter bar;
- (c) a circular cutting knife rotatably mounted on said cutter head and defining a cutting knife plane;
- and
- (d) a connecting plug assembly including
- (1) a guide pin positioned in the end-to-end aligned first and second bores for connecting said adjustment element with said cutter head;
- said first and second bores defining a plug-in direction for said guide pin;
- said plug-in direction lying in said cutting knife plane;
- and
- (2) a locking component having a tightened state and a released state;
- in said tightened state the locking component engaging said guide pin and clamping said adjustment element and said cutter head to one another through said guide pin;
- in said released state of said locking component said cutter head being removable from said adjustment element;
- (3) a first surface forming part of said adjustment element;
- and
- (4) a second surface forming part of said cutter head;
- said first and second surfaces facing one another;
- in said tightened state said locking component clamping said first and second surfaces to one another.

- (3) a locking component having a tightened state and a released state;
- in said tightened state the locking component engaging said guide pin and clamping said adjustment element and said cutter head to one another through said guide pin;
- in said released state of said locking component said cutter head being removable from said adjustment element;
- (4) a first surface forming part of a circumferential surface portion of said cross bolt;
- and
- (5) a second surface forming part of said cutter head and having a shape conforming to said first surface;
- said first and second surfaces facing one another;
- in said tightened stat said locking component clamping said first and second surfaces to one another.
