Abstract
A method and apparatus for the production of reinforced plastic objects uses a body form around which a casing having a cover is placed. The cover includes two cover units which between them defines an opening having an adjustable size and position. The opening provides access into the body form so that reinforced plastic material may be applied therein. The size of the opening is minimized to reduce the amount of environmentally harmful substances escaping therefrom, such as styrene. The position and size of the opening relative to the body form is adjustable to provide a convenient access into the body form.
Claims13
A method for production of large objects of plastic material with minimal escape of harmful substances to the environment, the method comprising:
- positioning a cover above a plastic application area, the cover including two cover units movable with respect to the plastic application area and each other to define an opening therebetween of an adjustable size and position,
- connecting exhaust air terminal devices below the cover,
- adjusting the size of the opening of the cover by manipulating the cover units,
- applying a plastic material to a body form in the application area through the opening in the cover, and simultaneously providing moderate air flow through the exhaust air terminal devices, and
- manipulating the cover units to adjust the size and position of the opening defined therebetween during the applying of the plastic material to minimize the size of the opening and thereby the escape of harmful substances to the environment.
An apparatus for production of large objects of plastic material with minimal escape of harmful substances to the environment comprising:
- a body form;
- a casing mountable on the body form;
- a cover placed on a top side of the casing, the cover having two cover units movable with respect to the casing and each other to define an opening therebetween of an adjustable size and position;
- and
- application means for applying a plastic material to the body form through the opening, said body form located in a reinforced plastic material application area, the casing having an exhaust air terminal device ending in an interior of the casing, and with the cover sealing against upper edges of the casing, the two cover units being individually movable on the top side of the casing and the opening being freely adjustable to size and position.
