Abstract
A method of cutting a sipe pattern into a tire tread includes feeding the tire tread through a leading roller assembly and toward a plunge cutting assembly along a tread plane, actuating the plunge cutting assembly to cut a first sipe at a first angle and a first depth using a blade, the blade operably coupled to the plunge cutting assembly, and actuating the plunge cutting assembly to cut a second sipe at a second angle and a second depth using the blade.

A method of cutting sipe patterns into tire treads, the method comprising:
- feeding a first tire tread through a leading roller assembly and toward a plunge cutting assembly along a tread plane in a feed direction;
- actuating the plunge cutting assembly to cut a first sipe in the first tire tread at a first angle and a first depth using a blade, the blade operably coupled to the plunge cutting assembly by a plunge fixture;
- rotating the plunge fixture relative to the feed direction;
- feeding a second tire tread through the leading roller assembly and toward the plunge cutting assembly along the tread plane;
- and
- actuating the plunge cutting assembly to cut a second sipe in the second tire tread at a second angle and a second depth using the blade, wherein the second angle is different from the first angle.
