Abstract
An extruded plastic strip (1) adapted for use in protecting the edge of an article having a curved surface: said strip including alongitudinal groove (6), a flexible covering portion (2) extending from one side of the longitudinal groove adapted to be placed over and conform with the curve surface of an article to be protected and a plurality of tabs (3-5) hinged to and extending from the other side of the longitudinal groove, wherein said covering portion includes a plurality of holes (9, 10) which are located at or proximate the outer most edge of the covering portion.

An extruded plastics strip adapted for use in protecting the edge of an article having a curved surface, said strip including a longitudinal groove, a flexible covering portion which extends from one side of the longitudinal groove and which is adapted to be placed over and conform with the curved surface of an article to be protected and a plurality of tabs hinged to and extending from the other side of the longitudinal groove;
- wherein said covering portion includes an outer most edge which is spaced from the longitudinal groove and wherein a plurality of holes are located at or proximate said outer most edge of the covering portion.
An extruded plastics strip adapted for use in protecting the edge of an article having a curved surface;
- said strip including a longitudinal groove;
- a flexible covering portion which extends from one side of the longitudinal groove and which is adapted to be placed over and conform with the curved surface of an article to be protected, and a plurality of tabs hinged to and extending from the other side of the longitudinal groove;
- wherein said covering portion includes an outer most edge which is spaced from the longitudinal groove and wherein holes of at least two different sizes are located at or proximate said outer most edge of the covering portion.
A method of simultaneously manufacturing two or more packaging strips, the method including the following steps:
- (i) extruding a plastics material and forming it into a substantially flat sheet of uniform thickness;
- (ii) forming a plurality of longitudinal grooves in said sheet;
- (iii) removing a number of separate and spaced areas of material from the sheet at locations extending from one side of each of the longitudinal grooves in which each of the removed areas has an outer edge parallel with but spaced from the respective groove which is wider than an inner edge of the removed area adjacent said groove;
- (iv) forming a number of separate and spaced holes in the sheet at positions located on the opposite side of each of the longitudinal grooves;
- (v) cutting the sheet into a plurality of separate strips in which each strip comprises one longitudinal groove and first and second straight edges which are parallel with each other and the longitudinal groove;
- wherein the first longitudinal edge of each strip is located in line with the outer edges of the removed areas so to form a plurality of tabs which extend from the respective grooves and wherein the spaced holes formed in the opposite side of each of the longitudinal grooves are positioned so to be between the longitudinal groove and the second longitudinal edge of each strip and wherein a plurality of said holes are located at or proximate said second longitudinal edge of each strip.
A method of simultaneously manufacturing two or more packaging strips, the method including the following steps:
- (i) extruding a plastics material and forming it into a substantially flat sheet of uniform thickness;
- (ii) forming a plurality of longitudinal grooves in said sheet;
- (iii) cutting the sheet into a plurality of separate strips in which each strip comprises one longitudinal groove and first and second straight edges which are parallel with each other and the longitudinal groove;
- (iv) removing a number of separate and spaced areas of material from each strip at locations extending from one side of the longitudinal groove of each respective strip so to form a plurality of tabs which extend from the groove of each of the strips;
- (v) forming a number of separate and spaced holes in each of the respective strips at positions located on the opposite side of each of the longitudinal grooves to that from which the tabs extend;
- wherein the spaced holes are formed in the portion on the opposite side of the longitudinal groove in each of the respective steps and wherein a plurality of said holes are located at or proximate the outer most edge of said portion on the opposite side of the longitudinal groove.
