Description

(54) A method of forming a reinforcing ring, for example, on a fiberglass container

It is an object of the present invention to provide a reinforcing ring on a fiberglass container, for example.

The prior art methods of forming a ring on a wound fiberglass container are based either on increasing the rigidity of the wall of the wound laminate container by winding a thicker laminate layer along the circumference of the wound laminate container, wrapping a shape advantageous profile in the laminate wall. the surface of the wound laminate container. ; The disadvantage of the first two methods is that they allow; to achieve only a relatively small increase in stiffness! and that the laminate used to form the ring is used to form the necessary ring ! it consumes a considerable amount and is a relatively expensive raw material for this purpose. The disadvantage of the third-! There are technological difficulties arising from the connection of the metal ring to the wound laminate container, the requirement for high accuracy of the ring production, difficult assembly on the wound laminate container produced, usually associated with partial or total dismantling of the wound laminate container from the winding machine .

The aforementioned drawbacks are eliminated by the method according to the invention, which consists in that the lower flange of the reinforcement ring is first provided with struts, for example by avoiding the die-cut portions of the lower flange, further wrapping the lower flange on e.g. The container is firmly attached and then fixed to the legs, for example by welding the upper flange of the reinforcement ring.

It is advantageous to arrange the uprights in two rows, with the essence of the invention not changing if they are only in one row or more than two rows.

This method of forming the reinforcing ring allows the formation of arbitrarily rigid rings on the wound laminate containers of circular and non-circular cross-section, does not require pre-fabrication of the exact shape of the rigid ring, the connection of the reinforcement directly follows the winding process.

1, 2, 3, 4, 5, 6 and 7 schematically show examples of a method of forming a reinforcing ring according to the invention.

A metal bottom flange 2 with a perpendicular protrusion is wound onto the wound fiberglass container 1 (FIG. 1) and then rewound with the laminate 5 and thereby firmly attached.

3, arranged in two rows on which the metal upper flange 4 is welded, thereby forming a reinforcing ring.

In the side view (FIG. 2), in the left half of the figure, the lower flange 2 with the webs 3 is wrapped on a wound laminate container 1, and in the right half the lower flange 2 is rewound with laminate 5 and the upper flange 4 is fastened to the webs.

'· READ Method of forming a reinforcement ring on, for example, a fiberglass container, characterized in that the bottom flange of the reinforcement ring is first provided with struts, for example by bending out the die-cut parts of the bottom flange, The front view and the plan view show the method of forming two rows of legs 3 (Fig. 3) by tethering to the lower flange Another possible way of forming two rows of legs 3 (Fig. 4, Fig. 5 and Fig. 6) is by avoiding the die-cut parts of the lower flange 2. To increase the axial stiffness of the reinforcement ring, it is advantageous to create two rows of legs 3 (Fig. 7). on the lower flange 2 at an angle other than a right angle. BACKGROUND OF THE INVENTION The flange is wrapped on a coil container and rewound with a laminate to fix it firmly to the coil laminate container, whereupon it is secured to the uprights, for example by tying the upper flange of a reinforcing ring.
