Claims8
An automatic ironing press comprising:
- a bedplate;
- a first ironing plate fastened to said bedplate;
- a pressing arm, having a first end and a second end, mounted onto said bedplate so as to rotate said first end between an opened or raised position with respect to said first ironing plate and a closed or thereupon superimposed position;
- a second ironing plate pivotally fastened to the first end of the pressing arm;
- means for the controlled heating of the material undergoing the ironing;
- driving means for supplying a driving force to move said pressing arm between the two positions of said first end;
- sensing means for the control of the operation of said driving means;
- and
- force transmitting means for transmitting force from said driving means to said pressing arm to move said pressing arm between the two positions of said first end, said force transmitting means applying a predetermined closing force to said arm when said first end is in said closed position, said force transmitting means comprising first and second connecting rods pivoted to each other to form a toggle joint, said toggle joint including a moveable pin adapted to operate said sensing means, the free end of said first connecting rod being pivotally connected to a guide means for moving said free end of said first connecting rod along a predetermined pathway, said guide means being operably connected to said driving means, the free end of said second connecting rod being pivotally connected to the second end of said pressing arm, and spring means connected to said guide means for applying a force to said moveable pin.
