<p>An apparatus for subdividing an axially moving product length is disclosed. The apparatus includes a pair of shear blades mounted on opposite sides of the path travelled by the product length. The shear blades are rotatable about non-parallel axes, and are arranged to effect a cutting action on the product length. The cutting action occurs along a reference line which intersects the path of product travel and which also bisects the angle included between the rotational axes of the cutting blades. The shear blades are driven continuously by a variable speed drive which is adjustable to equate the peripheral speed of the blade portions cutting the product with the linear speed of the product. The lengths of the resulting subdivided product sections can thus be varied by shifting the point at which the path of product travel intersects the aforesaid reference line and by making a suitable adjustment to the rotational speed of the shear blades.</p> |
