Abstract A traction mat for placement beneath the driving wheel of an automobile disabled on an ice- or snow-covered road. The mat comprises an inexpensive, one-piece, expendable elongate flat sheet of expanded metal such as metal lath, having a substantially rectangular shape and characterized by a plurality of slit portions formed by transverse slits in the metal. The sheet has a pair of opposite, longitudinal edge or margin portions formed by cutting across the sheet. This normally would result in a plurality of sharp protrusions which are formed by the cutting. To prevent injury to the user and daage to surrounding objects from scratching by the protrusions, a plastic substance is applied to the sharp protrusions, preferably by dipping the latter into a bath of plastic in a molten state and allowing the plastic substance to solidify, whereby the protrusions become coated with beads or globules of plastic.

A traction mat for placement beneath a driving wheel of an automobile disabled by slippery road conditions, comprising in combination: a. a unitary, one-piece, elongate sheet of expanded sheet metal of substantially rectangular shape, having a multiplicity of slit portions formed by traverse Slits, each of said slit portions having a pair of sharp-cut edges respectively presented at opposite sides of said sheet, the edges at one side being adapted for engagement with an icy road surface and the edges at the other side being adapted for engagement with the driving wheel of the automobile, said sheet having a pair of opposite longitudinal edge portions formed by cutting across the sheet, forming thereby a plurality of sharp-cut protrusions defining said edge portions; and b. encapsulating means for covering said protrusions along said longitudinal edge portions of the sheet with a protective layer of material which is relatively soft to the user''s touch, said encapsulating means comprising protective beads disposed along the opposite longitudinal edge portions of said sheet, said beads being adhered to said metal protrusions and enclosing the sharp-cut edges thereof and said beads comprising globules of synthetic plastic substance adhered to said protrusions by dipping the latter into the plastic substance while said plastic substance is in a molten state.
