Abstract
A press (11), more particularly usable as a platen press for woodworking, produces the pressing pressure by two superimposed rows (20,21) of hoses (19), which are filled with compressed air. An intermediate plate (17) ensures a pressure compensation. The pressing surfaces are formed by heating plates (29), the lower plate being partly extractable over the press frame, so as to facilitate loading and cleaning.
Claims11
A platen press, comprising:
- (a) at least one vertically movable press plate;
- (b) a press drive for moving said press plate, and comprising at least two overlying rows of laterally disposed, pneumatically inflatable hoses, the hoses of each row residing adjacent to each other;
- and
- (c) at least one vertically movable, rigid intermediate plate interposed between the at least two hose rows, and extending over the full width of the hose rows in a direction transverse to the hoses.
1 more element
A platen press, comprising:
- (a) at least one movable press plate;
- (b) a press drive for moving said press plate, and comprising at least two overlying rows of laterally disposed, pneumatically inflatable hoses, the hoses of each row being alternately laterally-displaced in a lengthwise direction, and having respective end pneumatic connections located at one end thereof;
- (c) the end connections being located at opposite ends of adjacent hoses of one of said at least two hose rows, and at opposite ends of adjacent hoses of a second, overlying one of said at least two hose rows;
- and
- (d) the end connections of overlying hoses of the first and second hose rows residing at opposite ends of the overlying hoses.
2 more elements
A platen press, comprising:
- (a) at least one movable press plate;
- (b) a press drive for moving said press plate, and comprising at least one row of laterally disposed, pneumatically inflatable hoses, the hoses being alternately laterally-displaced in a lengthwise direction and having respective end pneumatic connections located at one end thereof;
- and
- (c) the end connections being located at opposite ends of adjacent hoses of the at least one hose row.
1 more element
A platen press, comprising:
- (a) at least one movable press plate supported by a press frame, said press plate including an insulating plate and a heating plate carried by the insulating plate, the heating plate being horizontally slidable relative to the insulating plate for movement between a press position, in which the heating plate resides substantially within the press frame, and a displaced position, in which the heating plate partially projects beyond the press frame;
- and
- (b) a press drive comprising at least one row of laterally disposed, pneumatically inflatable hoses for moving said press plate.
A platen press, comprising:
- (a) at least one movable press plate;
- (b) a press drive for moving said press plate, and comprising at least two overlying rows of laterally disposed, pneumatically inflatable hoses, and a pressure takeover valve for maintaining pressure in the hoses above a predetermined value following pressure build-up in the hoses.
