Abstract

A process of manufacturing a ski, particularly a laminated ski, which is composed of a plurality of components, and a ski manufactured by that process. In the process, the components of the ski are placed into a mold, which is adapted to be evacuated, and the mold is subsequently evacuated. A liquid binder, such as a liquid resin, is supplied to the mold during or after its evacuation. Air is sucked from the mold at one end of the longitudinal extent of the ski. The liquid binder is supplied to the mold at the other end of the longitudinal extent of the ski. In the finished ski a strip of solidified binder extends in at least one vertical or horizontal longitudinal plane of the ski, preferably in a central longitudinal plane of the ski, over at least part of the length and preferably over at least one half of the length of the ski.

Dependent claims

A process of making a ski comprising the steps of:

a. placing the components of the ski comprising edge members, top and bottom members, intermediate layers and a core member which defines a longitudinal passage into a mold which is adapted to be evacuated and which includes a suction line at one longitudinal end to provide communication between the interior of the mold and a source of vacuum, and which includes a binder line at an opposite longitudinal end to provide communication between the interior of the mold and a source of liquid binder material,
b. closing and airtightly sealing the mold,
c. evacuating the air from the mold by applying a vacuum to the vacuum line, and
d. supplying liquid binder material to
said mold through the binder line, whereby the air is evacuated from the mold at one end of the longitudinal extent of the mold and whereby the liquid binder supplied to the mold at the other end of its longitudinal extent flows through the longitudinal passage of the core and fills the joints between the components of the ski to join said components so that they are firmly held together in a final ski structure.
