Abstract
An edge protector for the edges of roll shaped articles, e.g. pallets, reeled steel and paper products is made from an elongated sheet (10) of plastics material, the sheet having an indentation (11) extending longitudinally along a major surface of the sheet and extending only partially into the thickness of the sheet. The indentation (11) divides the sheet into webs (12, 13) which are folded into an L-shape.
Claims21
A method of protecting the edge portion of an article by means of a generally L-shaped edge protector, the protector being formed from a length of plastics sheet material having an indentation extending longitudinally along a major surface of the length and extending only partially into the thickness of the length whereby there is no deformation of the opposite major surface, the indentation dividing the length into web portions, the method comprising:
- locating a reel of the edge protector adjacent the article whose edge is to be protected;
- unreeling an unformed (flat) length portion of the reel and advancing it towards the article;
- passing the length portion through a former to bend one web portion relative to the other to form a generally L-shape edge protector;
- and
- applying an L-shaped edge protector along the edge of the article;
- wherein the thickness defined by the major surfaces of the edge protector in one of the web portions tapers toward a free edge of said web portion, away from the indentation.
An edge-protector, comprising an elongate sheet of plastics material, the sheet having an indentation extending longitudinally along a major surface of the sheet and extending only partially into the thickness of the sheet, whereby there is no deformation of the opposite major surface, the indentation dividing the sheet into two web portions, the sheet being folded about the line of the indentation into a substantially L-shaped cross-sectional shape to provide the edge-protector;
- wherein the thickness defined by the major surfaces of the edge protector in one of the web portions tapers toward a free edge of said web portion, away from the indentation.
A reel of plastics sheet material, the sheet having an indentation extending longitudinally along a major surface of the sheet and extending only partially into the thickness of the sheet, whereby there is no, deformation of the opposite major surface, the indentation dividing the sheet into two web portions, a length of the sheet when pulled off the reel being foldable about the line of the indentation to form an edge-protector of substantially L-shaped cross section;
- wherein the thickness defined by the major surfaces of the sheet in one of the web portions tapers toward a free edge of said web portion, away from the indentation.
A reel of plastics sheet material, which is deformable, the sheet having an indentation extending longitudinally along a major surface of the sheet and extending only partially into the thickness of the sheet, whereby there is no deformation of the opposite major surface, the indentation dividing the sheet into two web portions, a length of the sheet when pulled off the reel being foldable about the line of the indentation to form an edge-protector of substantially L-shaped cross section, the web portions of which remain at an angle to each other for a significant period of time;
- wherein the thickness defined by the major surfaces of the sheet in one of the web portions tapers toward a free edge of said web portion, away from the indentation.
An edge-protector for protecting an edge portion of an article, said edge-protector comprising an elongate sheet of plastics material having an indentation extending longitudinally along a major surface of a length of the sheet and extending only partially into the thickness of the length, an opposite major surface of said sheet being formed without any deformation in a region coextensive with the indentation formed in said major surface, said indentation dividing the length into web portions, said sheet being foldable about the line of the indentation into a substantially L-shaped cross-sectional shape to provide the edge-protector;
- wherein the thickness defined by the major surfaces of the length of the sheet in one of the web portions tapers toward a free edge of said web portion, away from the indentation.
