Abstract

The invention relates to a transportation system for annealing a glass container having a barrel and two extremities, said transportation system including a lath provided with at least two non-metallic inserts, the at least two non-metallic inserts being positioned such that, when a glass container is seated on said transportation system, said glass container is exclusively held by contact between said at least two non-metallic inserts and said barrel in substantially horizontal position which is fixed relative to the lath. The transportation system further includes securing means configured to reversibly firmly secure a clipping portion of said at least two non-metallic inserts into a respective slot of the lath.

Claims

1. A transportation system for annealing a glass container having a barrel and two extremities, said transportation system comprising:

a lath provided with at least two non-metallic inserts, the at least two non-metallic inserts being positioned such that, when a glass container is seated on said lath, said glass container is exclusively held by contact between said at least two non-metallic inserts and said barrel in a substantially horizontal position which is fixed relative to the lath; and

a securing element configured to reversibly firmly secure a clipping portion of said at least two non-metallic inserts into a respective slot of the lath.

2. The transportation system according to claim 1, wherein the slots are V-shaped.

3. The transportation system according to claim 1, wherein the lath further comprises two side portions and wherein the clipping portion of the inserts further comprises two abutment edges, each abutment edge being in abutment on one of the side portions of the lath, the two side portions and the abutment edges forming part of said securing element.

4. The transportation system according to claim 1, wherein the securing element comprises two oblique arms protruding into the slot in tight frictional contact with a lateral edge of the clipping portion of a respective insert accommodated in the slot.

5. The transportation system according to claim 1, wherein the inserts are made of carbon or ceramic.

6. The transportation system according to claim 1, wherein the inserts further comprise a seat portion having at least one seat intended to contact part of a glass container barrel.

7. The transportation system according to claim 6, wherein the at least one seat has a curved edge.

8. The transportation system according to claim 1, wherein the lath is made of stainless steel.

9. The transportation system according to claim 1, wherein the lath further defines a longitudinal symmetry axis and wherein the at least two parallel slots are perpendicular to said longitudinal symmetry axis.

10. The transportation system according to claim 1, wherein the lath comprises a central portion extending along a longitudinal axis of symmetry of said lath and two side portions located on both sides of said central portion, and the parallel slots extend through said central and side portions of the lath.

11. The transportation system according to claim 1, further comprising glass containers having a barrel and two extremities, wherein each glass container lies on at least two inserts only by a contact between said barrel and each of said at least two inserts.

12. A method for annealing a glass container having a barrel and two extremities, the method comprising:

providing a transportation system according to claim 1,

seating a glass container onto at least two non-metallic inserts firmly secured to the lath of the transportation system, so that the glass container is exclusively held by contact between said at least two non-metallic inserts and said barrel,

carrying the at least one glass container toward an annealing oven via the transportation system, said at least one glass container being motionless relative to the transportation system.
