Abstract

A cylindrically shaped body of a two-component adhesive material includes at least one web wound spirally around a central axis so that the web forms a number of overlapping layers in the radical direction of the body. The two-component adhesive material includes a resin component and a hardener component. A layer of each component is coated on the web. When the web is wound it separates the layers of the two different components so that they do not intermix. The cylindrical body can be laterally enclosed in a sheath and/or its transverse ends can be capped or coated to prevent intermixing of the components.

Claims

1. An adhesive body for securing an anchor bolt within a borehole comprises at least one web material section wound around itself about a central axis so that from the central axis radially outwardly said web material section is in overlapping relationship to itself, wherein the improvement comprises an adhesive material including a resin component and a hardener component, said resin component and hardener component each coated directly on said at least one said web forming a layer of each said component on said at least one web with said at least one web forming the sole separating layer between said component layers so that said resin and hardener components are maintained in separated relation for preventing intermixing of said components prior to use of the adhesive body for securing an anchor bolt within a borehole, and said web material being folded over upon itself so that a double layer of said component of adhesive material is located between the doubled over section of said web material.

2. An adhesive body, as set forth in claim 1, wherein said body has a generally cylindrically shaped exterior configuration.

3. An adhesive body, as set forth in claim 2, wherein said at least one web material section comprises a single web material section with each of its opposite face surfaces coated directly with a different one of said adhesive material components.

4. An adhesive body, as set forth in claim 2, wherein a sheath at least partially encloses the cylindrically shaped said body and said sheath being impermeable to said resin and hardener components.

5. An adhesive body, as set forth in claim 1, wherein said at least one web material section comprises two web material sections, each said web material section having a different said adhesive material component coated directly on one face surface thereof with the other face surface thereof being uncoated, and said two sections of web material being placed one on top of the other so that the uncoated surface of one contacts the coated surface of the other forming in a series layer arrangement a first web material section, a layer of one of the adhesive material components, a second web material section and a layer of the other one of the adhesive material components.

6. An adhesive body, as set forth in claim 1, wherein said web material is formed of a material impermeable to said resin and hardener components.

8. An adhesive body, as set forth in claim 1, wherein said web is formed of a material impermeable to said resin and hardener components.

9. An adhesive body, as set forth in claim 8, wherein said web section is formed of one of the group consisting of a plastics material sheet, a sheet material formed of glass fibers, a sheet material formed of a fibrous material, a fabric and a paper.

10. An adhesive body, as set forth in claim 9, wherein said web section is formed of an impregnated paper.

11. An adhesive body, as set forth in claim 10, wherein said web section is formed of an oiled paper.

7. An adhesive body for securing an anchor bolt in a borehole comprising at least one web material section, a two-component adhesive material comprising a resin component and a hardener component, wherein the improvement comprises that said resin component and hardener component are coated in layers directly on said at least one web in separated relationship so that said web is in direct contract with and separates said components whereby they do not intermix, said web section and said resin and hardener component layers are wound around a central axis forming a generally cylindrical body of alternating layers of said web, said resin component, and said hardener component with said layers wound in overlapping spiralling relation and with said at least one web section separating said resin and hardener components so that prior to the insertion of an anchor bolt into the adhesive body for mixing said resin and hardener components the components are separated from one another only by said web section, said web section has two longitudinally extending face surfaces and two longitudinally extending edge surfaces, said resin component coated on one of said face surfaces and said hardener component coated on the other said face surface, and said web section being wound so that at least the layer of one of said components contacts the same layer of said component as said web section is spirally wound.

12. A method of forming an adhesive body for use in securing an anchor bolt in a borehole comprising directly coating separate face surfaces of a web material each with a different component of a two-component adhesive material, winding the web material around a central axis with the web material being wound around itself in an outwardly spirally arrangement and with the web material separating adjacent layers of different adhesive material components, folding the web material over upon itself so that the same component of adhesive material is located between the folded over face surfaces of the web material section and winding the web to a selected outside diameter.

14. A method, as set forth in claim 12 or 13, including the step of winding the web about a central axis extending in the long direction of the web for forming a continuous cylindrical body, and cutting the continuous cylindrical body into the desired size of adhesive body to be employed.

13. A method of forming an adhesive body for use in securing an anchor bolt in a borehole comprising applying a coating of a different one of the adhesive material components to one surface of two separate sections of web material so that each section is coated on one face surface and is uncoated on the other face surface, placing one of the coated web sections on top of the other coated web section so that the coated face surface on one contacts the uncoated face surface on the other, and winding the two coated material sections to a select outside diameter so that each said layer of the coated adhesive material is separated from the other said layer by a web material section.
