Abstract
A method of manufacturing a blade of a hockey stick or the like, a blade and a blade core used in the blade. The blade core is manufactured of a plastic material, recesses for arranging a strengthening layer being provided in vertical sides thereof. According to a preferred embodiment of the invention, the sides of the blade core are provided with two recesses within each other. Furthermore, a reinforcing element cut off from a wooden plate can be used as an inner strengthening layer of the blade core.
Claims11
A method of manufacturing a blade of a hockey stick or the like, the method comprising the following steps:
- arranging one or more strengthening layers in a first and a second vertical side of a core of the blade premanufactured of a wear-resistant plastic material such that at least at a lower edge of the blade, the blade core extends farther than the strengthening layers and forms a wear-resistant border for the edge,
- providing at least one side of the blade core with a flat recess which is parallel with a surface of the side and which is at least approximately similar in length to the blade core,
- embedding at least one of the strengthening layers in said recess to strengthen the blade.
A blade of a hockey stick or the like, the blade comprising a core of the blade and one or more strengthening layers arranged in a first and a second vertical side of the blade core, the blade core being made of a wear-resistant plastic material and at least at a lower edge of the blade, the blade core extending farther than the strengthening layers, whereby the lower edge of the blade is provided with a wear-resistant border, and at least one side of the blade core being provided with a flat recess parallel with a surface of the blade core, and at least one of strengthening layers in the side of the blade being arranged in said recess.
A blade of a hockey stick or the like, the blade comprising a core of the blade and one or more strengthening layers arranged in a first and a second vertical side of the blade core, the blade core being made of a wear-resistant plastic material and at least at a lower edge of the blade, the blade core extending farther than the strengthening layers, whereby the lower edge of the blade is provided with a wear-resistant border, and wherein one side of the blade core is provided with a flat recess parallel with a surface of the side and at least approximately similar in length to the blade core, the blade further comprising:
- a strengthening element arranged in the recess of the blade core, the strengthening element being substantially of a similar shape to that of a profile of the recess in the blade core and made of a plastic material having a lower density than that of the blade core, and further, an outer surface of the strengthening element being provided with a cover layer made of reinforcing fibers and a plastic material, and
- at least one outer strengthening layer attached to the first and the second sides of the blade core and having a substantially similar profile to that of the blade.
A blade core comprising a first and a second vertical side, a lower edge to be arranged against a playing surface and an upper edge opposite to the lower edge, a tip and a heel, the blade core being manufactured of a plastic material, and at least one side of the blade core is provided with a flat recess for enabling a strengthening layer to be arranged therein, the recess being parallel with a surface of the blade core.
