Mat-base assembly comprises a base including a sheet integrally formed of an elastomeric polymer, a picture frame-like projection formed on the periphery of the sheet and a mat-containing portion formed on the inner side of the peripheral projection, a dust-controlling mat contained in the mat-containing portion and a temporary anchoring mechanism for anchoring detachably the base and mat at a plurality of points on the peripheral edge of the sheet, wherein an anchoring element comprising engaging pieces implanted on a base fabric is fixed to the base, a fiber loop element engageable with the engaging pieces is sewn to the mat and the peripheral portion of the anchoring element is fusion-bonded to the base sheet while in the remaining portion of the anchoring element, the engaging pieces are left as they are. In this mat-base assembly, the durability of the anchoring mechanism is highly improved and good adaptability to the operation of attaching and detaching the dust-controlling mat is maintained for a long time. Furthermore, movement of the dust-controlling mat or roll-up of the corner portion of the mat can effectively be prevented.

A mat-base assembly which comprises a base comprising a sheet, a picture-frame-like projection formed on the periphery of the sheet and a mat-containing portion formed on the inner side of said peripheral projection, said sheet, peripheral projection and mat-containing portion being integrally formed from an elastomeric polymer, a dust-controlling mat contained in said mat-containing portion and a temporary anchoring mechanism for anchoring detachably said base and mat at a plurality of points on the peripheral edge of the sheet, wherein an anchoring element comprising engaging pieces implanted on a base fabric is fixed to said base, a fiber loop element engageable with said engaging pieces is sewn to said mat and the peripheral portion of the anchoring element is fusion-bonded to the base sheet at a temperature higher than the softening point of the polymer constituting the base sheet but lower than the melting or softening point of the base fabric of the anchoring element so that the engaging pieces in the peripheral portion are crushed or stuffed toward the base sheet while in the remaining central portion of the anchoring element, the engaging pieces are left as they are, whereby the mat can be securely but detachably anchored to the base when the mat is seated within said mat-containing portion with the engaging pieces of the anchoring element engaging the fiber loop element.
