The present invention relates to a new process for manufacturing cylindrical cork bodies and the final product resulting from this new process for manufacturing closures for beverages (e.g., carbonated wines, still wines, beers, etc.) or washers which are used in multi-piece cork stoppers and which is based on the lamination of a sheet of natural cork after it has been cooked and flattened (1), with strips of a thickness of between 0.06 mm and 2 mm (2), the individual cleaning of each strip (3), the gluing of the thin strips with specific food-grade glues used in the cork sector, which after being selected (4), are glued in such a way that the natural irregularities of the cork are offset, making it possible to compose a homogeneous cork parallelepiped (5).Next, the parallelepiped composed of microlayers of cork is sliced ​​and tubed according to the traditional manufacturing process for natural corks or washers. The tubing in the production process can be carried out parallel to the direction of the laminated sheets (6), perpendicularly (7), or obliquely (8). The corks and washers produced by this new manufacturing process exhibit all the physical and visual characteristics of natural cork.

This invention relates to the field of engineered wood processing technology, specifically to a method for preparing a high-resistance photochromic cork-based board, comprising the following steps: S1. Preparation of a modifier; S2. Preparation of a modified adhesive; S3. Preparation of the board. This invention significantly improves the photochromic resistance of cork-based boards by adding a photochromic modifier to the adhesive used for the cork-based board, and the operation is simple. The added modifier does not change the original color of the cork-based board and has no effect on subsequent processing, such as dyeing and finishing.

A cork (15) intended for bottling still wines, characterized in that it comprises cork strips (11) joined laterally by a polyurethane binder so as to form a plurality of cork strips, the cork strips (11) being arranged so that their thickness is perpendicular to the axis of the cork, at least one lateral cork strip (13) joined by a polyurethane binder to each face of the plurality of cork strips, leaving the entirety of the cork strips (11) exposed, the lenticels possibly present in the cork strips (11) extending parallel to the thickness of the strips while those in the lateral cork strips (13) extend perpendicular to the thickness of the strips, so that all the lenticels of the cork are arranged perpendicular to the axis of the cork in order to limit the variation of oxygen permeability from one cork to another.

The utility model relates to the technical field of cork cutting machines, and discloses a cork cutting machine which comprises a bottom frame, a waste collecting hopper is arranged on the bottom frame and used for collecting wood chips, and a translation frame is arranged on the waste collecting hopper in a sliding mode. The translation frame slides back and forth on the waste collecting hopper by arranging idler wheels at the bottom, a sliding way matched with the idler wheels is arranged on the side edge of the waste collecting hopper, and a driving motor and a saw blade are further arranged on the bottom frame. By means of the structural design of the translation frame, the supporting plate and the side baffles, cork wood is supported and synchronously displaced, and compared with a cutting mode that a traditional cutting machine only moves wood, the cork wood cutting device can achieve the more accurate and convenient cutting effect.
