It appears you are referencing an industrial lining trimming machine (commonly used in shoemaking for leather midsoles, rubber outsoles, and shoe vamps),

The primary differences in mechanics, cutting action, and best-use cases between round knives and straight knives depend on whether they are configuration components of an upper/lower dual-blade table

Dual-Blade Trimming Machines (Upper & Lower Blades)

In specialized shoe manufacturing, an integrated inner lining trimming machine utilizes a combined configuration of a straight blade and a round (circular) blade working together as an upper and lower assembly:

The Round Knife (Circular Blade): Serves as the continuous rotary driving force. It feeds and shears the tough leather or rubber cleanly along a smooth contour.
The Straight Knife: Often serves as a stationary counter-blade or an alternating guide piece.
Up and Down Action: The material is fed between the upper and lower table setup. The shearing compression removes excess lining, vamps, or mid-soles flush to the edge without fraying or burrs.

Standalone Cutting Machines: Round vs. Straight

If you are deciding between standalone industrial cutting tools, the mechanisms differ

Feature	Round Knife Machine (Rotary)	Straight Knife Machine (Reciprocating)
Blade Motion	Continuous circular rotation	Vertical up-and-down (reciprocating)
Best Used For	Straight lines and gentle, large-radius curves	Intricate patterns, sharp corners, and tight angles
Material Thickness	Low plies, thin layers, or single-ply tough materials	High ply stacks (bulk cutting up to 10+ inches thick)
Maneuverability	Pushed through fabric, but limited in sharp corners	Highly maneuverable around complex stencils

Mechanism Highlights

Round Knife Machine: Driven by an internal motor that spins a circular blade. Because it relies on a steady rotation against a baseplate, it is unmatched for slicing long, clean, straight paths. It will jam if forced to make sudden, sharp turns.
Straight Knife Machine: Driven by a crank mechanism that transforms motor rotation into a rapid, vertical up-and-down sawing action. Because the blade is vertical and narrow, you can rotate the machine effortlessly mid-cut to follow complex, jagged patterns.
