A strap joint rotating assembly is for use with a strapping machine. The strapping machine has a feed head for feeding the strapping material into the strapping machine, a strap chute through which the strapping material is passed and a sealing head to seal overlapping courses of the strapping material to one another to define a strap loop having a seal and defining a strap loop plane. The strap joint rotating assembly includes a driven wheel having an axis of rotation generally perpendicular to the strap loop plane and a pinch wheel that has an axis of rotation and is carried on a wheel block. The wheel block pivots to move the pinch wheel into and out of the strap loop plane. The pinch wheel, when in the strap loop plane, has its axis of rotation parallel to the axis of rotation of the driven wheel. The pinch wheel is further movable toward the driven wheel to pinch the strap between the driven wheel and the pinch wheel. The driven wheel is driven to rotate the strap loop around the load.

A limited slip differential having a carrier with a plurality of recesses disposed symmetrically relative to a gear opening. The gear opening having a gear diameter, and each of the plurality of recesses having a recess diameter. The gear diameter intersecting the recess diameter of each of the plurality of recesses at corresponding first and second intersections, an acute angle between a line tangent to the recess diameter at the first intersection and a tangent line of the recess diameter along which first and second chamfers extend is between approximately 30 degrees and approximately 32 degrees.

Limited slip differential

A limited slip differential having a carrier with a plurality of recesses disposed therein about a rotation axis thereof, each recess having an open side portion with generally opposite first and second edges substantially parallel to the rotation axis, a chamfer disposed along each of the first and second edges, and a planetary gear disposed in each of the plurality of carrier recesses having a portion protruding from the open side portion thereof.
