摘要:
A laminating machine of the type which laminates documents between sheets of plastic or a document to a substrate comprising a housing together with a first set of rolls within the housing adapted to guide the material to be laminated between upper and lower heating platens and a second set of rolls within the housing arranged to receive the material from the platens. The first set of rolls, the platens and the second set of rolls define a passage through the housing. End supports for the rolls are provided in the housing defines. The rolls are rotatably supported between the end supports. A drive motor is connected to one of the rolls at one of the end supports, and gearing means are positioned on the rolls at the other of the end supports for transmitting rotation of the driven roll to the other rolls. The upper rolls of each pair are journaled in bearing arms which are pivoted to the end supports to permit acceptance of thick substrates. Auxiliary drive means are provided to maintain all rolls in synchronization when a thick substrate causes the gears to move out of mesh.

A laminating machine of the type which laminates documents between sheets of plastic or on a substrate comprising a housing, first and second sets of upper and lower rolls within said housing having end shafts, one of the sets of rolls arranged to receive material to be laminated and move the material to the other of the sets of rolls, spaced apart end supports are in housing rotatably supporting the end shafts, drive means are connected to the lower rolls of each pair, to drive the lower rolls, the upper rolls of each pair are mounted in the end supports to move upwardly to accommodate material of variable thickness, resilient power transmission means are connected between the upper rolls and the lower rolls and driven from the lower rolls to maintain synchronization of rotation of the upper rolls with the lower rolls and to bias the upper rolls downwardly while permitting the upper rolls to move upwardly to an extent dependent on the thickness of material passing between the pairs of rolls.

摘要:
A chemical delivery and foam generating system having a high pressure pump for pressurizing a wash fluid source to a pressure at or above 500 psi in a commercial car wash. The system includes a first eductor in fluid communication with the high pressure pump, the first eductor having at least one inlet for receiving a liquid chemical from bulk supply and located at an off-board position. A second eductor is positioned at an on-board position and includes one inlet for receiving ambient air. An elongated high pressure hose extends between the first eductor and the second eductor. At least one foam discharge nozzle is coupled to the second eductor to dispense foamed chemical onto the vehicle.

摘要:
An automotive vehicle washing system includes a frame comprising a bridge member end opposed and support sections mounted for linear reciprocating movement on spaced apart support rails. Pivoting washing nozzle support arms are mounted on the bridge section and are interconnected by a drive motor and drive pulleys to move in opposite directions to wash the sides and opposite ends of a vehicle. Each arm includes movable arm sections supporting spaced apart nozzle assemblies which may move toward each other or away from each other to size a vehicle according to its width. Each arm includes opposed elongated beam members which also provide fluid conducting passages for conducting washing fluids to the nozzle assemblies. Certain ones of the nozzle assemblies are drivenly connected to an oscillating servomotor. The servomotor is also used to position the pivoting arm sections through a lost motion coupling and a gear drive unit.
