Abstract: Sectional spray collector arched shields are mounted above a vehicle wheel and extend around approximately one-eighth to one-half of the vehicle wheel circumference. Each shield includes adjacent, downwardly flaring collector channels running circumferentially of shield. The collector channels have apertures in their crests and the aperture marginal portions are formed by flanges to divert the spray into troughs between adjacent collector channels. Water from the troughs is collected in runoff gutters inclined inboard to dump the drainage water beneath the vehicle.

Abstract: Box parts such as box bottoms and box lids are fabricated from notched blanks of plastic sheet material.Relatively large boxes can be fabricated and the blank feed mechanism is actuated by a crank mechanism that runs at twice the speed of a main, one revolution per cycle drive shaft. An extension blank pusher can be added to produce smaller boxes. The tab folders have solvent applicators formed as grooved metal bars associated with a centralized solvent delivery and recovery system. The transverse folding dies are heated with a flexible, rope-like heating element to facilitate changes in die length. The feeding apparatus includes cam operated, vacuum cup lifter arm assemblies which lift the top blank from a stack and present it to vacuum cups on the feed pushers. These assemblies are longitudinally adjustable. The anvils that cooperate with the tab folders have heated bodies, but their clamp surfaces are insulated from the bodies.
