Abstract: An improved mat is disclosed. Long and short legs support the mat and cause it to feel resilient although it is fabricated from hard rubber. Ribs prevent the mat from embedding within grating. Grit is selectively placed upon the mat and physically supported. Adhesive for bonding the grit is retained by retention lips. A process for filling grit trenches uses a robot to selectively place adhesive upon the mat. An adhesive dispenser is attached to the robot and the robot is appropriately programmed.

Abstract: An improved mat is disclosed. Long and short legs support the mat and cause it to feel resilient although it is fabricated from hard rubber. The mat has drain holes on vertical surfaces. Ribs prevent the mat from embedding within grating. Grit is selectively placed upon the mat and physically supported. Adhesive for bonding the grit is retained by retention lips. Also disclosed is a process for creating drain holes on vertical surfaces of mats by attaching a grooving tool to a robot and programming the robot to cut through molded mat channels to create the desired drain holes. An additional process uses the robot to selectively place adhesive upon the mat. An adhesive dispenser is attached to the robot and the robot is appropriately programmed.

Abstract: A mat perimeter system comprising a mat module, a connector, a resilient border and a resilient corner is disclosed. The mat module has upstanding studs attached on one edge and matching stud receptacles formed into another edge. The studs fit within the stud receptacles allowing the building of a modular mat system. Connectors having two spaced apart rows of studs attached to a base fit within the stud receptacles and allow the creation of another row of studs. Borders and corners fit over the studs to create a desirable perimeter. The studs have locking lips for interlocking with lip recesses formed within the stud receptacles and for interlocking with stud slot lip recesses formed into the borders and corners.
