摘要:
The subject matter of the invention is a bonding press for bonding shoe soles to lasted uppers, comprising a fixed bed structure (1) including an exchangeable receptacle plate (6, 9) into the padded opening (8) of which a lasted upper (7) is inserted and fixed with the sole laid thereon and facing upwards, further comprising a pressing pad (2) to which a pressurized medium may be applied, the dimensionally stable cowl (10) of said pad being hingedly joined to the bed structure (1) and hermetically sealed towards the bottom by a flexibly expandable diaphragm (12), and comprising linear drive means (3) mounted to the bed structure for pivoting the cowl (10) and for producing the closing force. In order to achieve secure fixing of the pressing pad (2) in the closed position thereof with relatively small driving forces and to prevent undesirable opening and closing movements of the pressing pad in the event of failure or breakage of single structural parts, the invention provides that the linear drive means (3) engage with the cowl ( 10) through an articulated lever mechanism including two toggle levers (17, 21), wherein the relative distribution of weight of the cowl and of the articulated lever mechanism is matched in such a way that there is a weight counterbalance in any open position of the cowl (10). In addition, an automatically operative safety means against upward pivoting of the cowl (10) due to internal pressure may be provided.
摘要:
A bonding press for cementing shoe soles to lasted uppers. A shoe support plate has an opening to receive the lasted shoe upper with the sole placed thereon. The lasted shoe upper is supported on a last support. A rigid press hood closed on the underside by a soft membrane, is selectively movable to a position to apply pressure to the sole in place on the upper. A control system has switching members for moving, releasing and filling the press hood with compressed air and venting the same. The control system also includes a switching valve adapted to be actuated by insertion of the shoe in the opening formed in the shoe support. The actuators and other elements of the system for controlling the movable press components are controlled by programmable control unit.

A gluing press for shoes or other similarly shaped workpieces having a pressure-medium operated pressure cushion whose highly resilient diaphragm fixes the sole to be attached during the gluing operation on the shoe upper placed on a last and retained in a shoe-receiving device, a feed movement taking place between the pressure cushion and the shoe-receiving device before the gluing operation. A switch is disposed on the shoe-receiving device the switch being constrainedly operated by the introduction of the upper shoe and switches on the drive for the closure movement of the operative parts of the gluing press formed on the pressure cushion and the shoe-receiving device. A safety device is connected to one of the operative parts of the gluing press which, when deflected by an obstacle in the path of movement of the movable part of the gluing press, switches off or reverses the drive.
