Abstract: A sheet material for roofing to be installed on a roof under an overlayment comprising a closed-weave woven having a top side and a back side; a thermoplastic layer affixed on the top side; and a water-based adhesive coating affixed on the back side. The sheet material is manufactured as a roll in which the thermoplastic layer isolates the water-based adhesive coating from an immediate environment when the sheet material is in a roll form.

Abstract: There is provided a slip resistant sheet material for roofing having a thickness and being adapted for a worker to walk thereon in his footwear. The slip resistant sheet material comprises a single layer of non-woven material comprising surface texture transverse to the thickness of the slip resistance material whereby, when the worker walks on the slip resistant non-woven sheet material, there exists friction between the footwear and the surface texture in the slip resistant non-woven sheet material thereby providing slip resistance.

Abstract: The present document describes a slip resistant sheet material for roofing having a thickness and being adapted for a worker to walk thereon in his footwear. The slip resistant sheet material comprises a base layer and a thermoplastic layer affixed to the base layer. The thermoplastic layer comprises embossments and corresponding depressions transverse to the thickness of the slip resistance material whereby, when the worker walks on the slip resistant sheet material, there exists friction between the footwear and the embossments in the thermoplastic layer thereby providing slip resistance.

Abstract: The present document describes a slip resistant sheet material for roofing having a thickness and being adapted for a worker to walk thereon in his footwear. The slip resistant sheet material comprises a base layer and a thermoplastic layer affixed to the base layer. The base layer and the thermoplastic layer define projections and corresponding depressions transversely to the thickness of the slip resistance material whereby, when the worker walks on the slip resistant sheet material, there exists friction between the footwear and a combination comprising the projections and the thermoplastic layer thereby providing slip resistance.

Abstract: The present document describes a protective wrapper for a roll having two ends and a length defining a distance between the two ends, the protective wrapper comprising: first one layer of paper material having two opposed edges and an edge strip at at least one of the two opposed edges of the first layer of paper material, the edge strip comprises one and only one layer of the paper material and the edge strip is for being inwardly crimped against one of the two ends; and a layer of protective material superposed to the first layer of paper material, the layer of protective material not overlapping the edge strip; wherein the first layer of paper material has a width greater than the distance between the two ends of the roll.

Abstract: The present document describes a slip resistant sheet material for roofing comprising a closed-weave woven comprising yarns of a first gauge and yarns of a second gauge greater than the first gauge. The yarns of the second gauge are interspersed in the closed-weave woven at a given interval with the yarns of the first gauge.

Abstract: A bag dispensing system has numerous thin plastic bags weakly attached together to form a bag pack, and a rack for supporting the bag pack and dispensing individual bags. Each bag has a tear-away release means which includes at least one centrally located opening for receiving a support finger of the rack, and is separated from an upper edge of the bag by a tear through portion. At least one pressure point is located adjacent the tear through portion. Each bag has a pair of opposed handles, each of which includes a flap-free opening for receiving a side support rod of the rack. The bag pack has successive overlying layers of thermoplastic film which form successive outside bag surface to outside bag surface contacts alternating with inside bag surface to inside bag surface contacts. Each layer of the bag pack is weakly joined to both adjacent layers without adhesive.
