Abstract: A corner post application system for a load having corners includes corner post applicators and moveable corner post holders. The corner post applicators include a corner post gripper configured to grasp a corner post, with the corner post applicators configured to move the corner post to a corner of the load. The corner post holders each have a clamp and are moveable between a retracted position and an engaged position, where in the engaged position the clamp is configured to engage a respective corner post to press the corner post against the load at the respective corner. When the corner post holders are in the engaged position the corner post applicators are configured to be retracted with the corner posts being held in engagement with the corners of the load by the corner post holders to enable an enveloping machine to initiate placement of a film over the load.

The cutting head has a body having a front end, a rear end, and a peripheral sidewall, a primary cutting insert and a pair of auxiliary cutting inserts. The primary cutting insert is cross-shaped with a central portion with a cutting tip and four cutting arms each with a cutting edge extending radially outward from the central portion past the peripheral sidewall. The auxiliary cutting inserts are spaced radially outward from the central portion and circumferentially from the radial cutting arms, and have a cutting edge extending radially outward past the peripheral sidewall. A pair of primary dust egress slots and a pair of auxiliary dust egress slots are formed in the peripheral sidewall and configured to channel debris from the front end to the rear end of the body.

A tapered web is formed in the flute portion, a thickness of the web at the tip of the working end is about 9% to 15% of the nominal diameter.

Abstract: A chisel includes an elongate shank portion composed of a first steel, and a working end portion composed of a second steel that is different than the first steel. The working end portion is joined to the shank and configured to chisel a workpiece. The joined shank portion and working end portion has been heat treated to cause the first steel of the shank portion to adopt a first microstructure comprising bainite, the second steel of the working end portion to adopt a second microstructure comprising martensite, and the working end portion to have a greater hardness than the shank portion.

Abstract: A passenger automotive vehicle wheel bearing assembly having improved impact Brinell resistance is provided. Due to a controlled gap between a rotating component and a non-rotating component or a vehicle suspension structure, the non-rotating component or the vehicle suspension structure is permitted to share impact loads caused by a sufficient radial or side impact (such as a pothole or curb impact) to the rotating component, thus preventing excessive loads from being transmitted to rolling elements, and providing greater resistance against Brinell impact damage that would generate a noise and/or vibration condition in the bearing assembly. Wheel bearing assemblies according to the invention provide increased impact Brinell resistance while avoiding excessive contact between the rotating component and the non-rotating component or the vehicle suspension structure during extreme cornering maneuvers.
