Abstract
The head of a head assembly for a cutting machine defines a first channel oriented at an oblique angle to an axis of movement of the assembly, a slide, mounted for slidable movement in the channel, between a withdrawn blade position and a plunged blade position, and a blade-holding magazine. The slide has a second channel extending substantially parallel to the first channel for receiving the blade-holding magazine, and the slide and head include cooperating mechanical elements for adjustably limiting the movement of the slide to the plunged blade position. Cooperating mechanical components also adjustably limit the depth of magazine insertion into the second channel.
Claims15
A head assembly for a cutting machine, comprising:
- a head having mounting means for movement of said head assembly on an axis, said head defining a first channel oriented at an oblique angle to said axis;
- and
- a slide mounted for slidable movement in said channel of said head between a withdrawn blade position and a plunged blade position, said slide having a second channel therein extending substantially parallel to said first channel for receiving a blade-holding magazine inserted thereinto, said slide and head having first cooperating mechanical means thereon for adjustably limiting the movement of said slide to said plunged blade position;
- wherein the blade-holding magazine is dimensioned and configured for slidable insertion into said second channel in said slide, said slide and magazine having second cooperating mechanical means thereon for adjustably limiting the depth of magazine insertion into said second channel;
- and
- wherein said assembly includes a linear motion support system for said slide, said support system comprising, on each of two opposite sides of said slide, an array of at least three elongate rectilinear elements mutually spaced to define a passage therewithin, and a multiplicity of bearing elements loosely stacked in columnar relationship within said defined passage.

A head assembly for a cutting machine, comprising:
- a head having mounting means for movement of said head assembly on an axis, said head defining a first channel oriented at an oblique angle to said axis;
- a slide mounted for slidable movement in said first channel between a withdrawn blade position and a plunged blade position, said slide having a second channel therein extending substantially parallel to said first channel, and said slide and head having cooperating mechanical means thereon for adjustably limiting the movement of said slide to said plunged blade position;
- and
- a blade-holding magazine dimensioned and configured for slidable insertion into said second channel, wherein the magazine includes a slot, a shoulder obliquely disposed relative to the slot and positioned adjacent one end of the slot, and means for securing a blade within the slot, wherein the shoulder is disposed such that the means for securing a blade within the slot holds a portion of a cutting edge of the blade in contact with the shoulder.
