## Abstract

A mat of a liquid-tight, flexible material is provided for the collection of fluid used to treat objects pulled onto the mat. In particular, the mat is used for the collection of deicing fluid during deicing of an aircraft. The mat comprises at least one discharge opening. The mat includes wires for stiffening the mat in the direction of travel on it. The mat may advantageously be formed with grooves for directing the treatment fluid to at least one discharge opening. For use in connection with large mats composed of mutually parallel webs there is provided a fixture for mutual fastening of the webs and sealing of the joint between the webs.

## Claims

### Claim 1

A mat for collecting deicing fluid during deicing of an aircraft rolled in a predetermined longitudinal direction of travel onto the mat comprising:
a bottom section made from a liquid-tight, flexible material, said bottom section including a pair of longitudinally extending edges that are spaced in a transverse direction of said mat;
an upper section made from a liquid-tight, flexible material, said upper section being formed with a plurality of grooves for drainage of deicing fluid, said grooves being longitudinally spaced and extending transversely across said mat, at least some of said grooves defining discharge outlets that open at said longitudinally extending edges; and
means for stiffening and preventing the mat from bulging, said means for stiffening and preventing bulging including a plurality of longitudinally extending, transversely spaced and substantially parallel steel wires embedded in said bottom section.

### Claim 2 (depends on 1)

A mat according to claim 1, comprising mutually parallel and transversely extending webs, wherein said webs are provided with engagement means along said longitudinally extending edges for engagement with fixtures adapted to affix the webs to each other and to a subadjacent layer on which the mat is placed and to seal the joints between the webs.

### Claim 3 (depends on 1)

A mat according to claim 1, wherein the mat surface between the grooves has upright, friction promoting members between which the deicing fluid may drain to the grooves.

### Claim 4 (depends on 2)

A mat according to claim 2, wherein the mat surface between the grooves has upright, friction promoting members between which the deicing fluid may drain to the grooves.
