Abstract
A laundry mangle has at least one mangling roller held in a working position inside a heatable trough by at least one carrying arm. The mangle roller and the trough are held in relative moveable positions by at least one adjusting member, delimiting together the inlet and outlet sides of a passage for laundry pieces. The adjusting member allows a force to be exerted on the mangling roller and/or trough that counteracts the frictional force generated during operation of the mangle, so that a constant or increasing ironing pressure towards the outlet side is set. The frictional force (R) generated during mangling is thus compensated, so that a gentle, wear-free mangling process is achieved. In addition, the mangling capacity is increased, compared with known mangles.
Claims8
Laundry mangle for counteracting a frictional force generated during service of the laundry mangle, said mangle comprising at least one mangle roller, at least one arm for supporting said mangle roller in a heatable trough in a service position, said mangle roller and said trough being movably positioned relative to each other, inlet and outlet passages for laundry articles provided between said mangle roller and heatable trough:
- a force generating mechanism which counteracts the frictional force generated during service of the laundry mangle comprising an adjusting device acting on a component selected from the group of components consisting of said mangle roller and said trough, wherein said adjusting device engages said supporting arm, and said supporting arm is swivelable about a point and movable with a movement selected from the group of movements consisting of translation and rotational movement in the service position:
- and wherein said trough is longitudinally movable and wherein said adjusting device acts directly on said trough.
Laundry mangle for counteracting a frictional force generated during service of the laundry mangle, said mangle comprising at least one mangle roller, at least one arm for supporting said mangle roller in a heatable trough in a service position, said mangle roller and said trough being movably positioned relative to each other, inlet and outlet passages for laundry articles provided between said mangle roller and heatable trough:
- a force generating mechanism which counteracts the frictional force generated during service of the laundry mangle comprising an adjusting device acting on a component selected from the group of components consisting of said mangle roller and said trough:
- wherein said adjusting device engages said supporting arm, and said supporting arm is swivelable about a point and movable with a movement selected from the group of movements consisting of translation and rotational movement in the service position:
- and wherein said adjusting device produces, relative to a driving torque of said mangle roller, a counter-torque which acts on a component selected from the group of components consisting of said mangle roller and said trough.
Laundry mangle for counteracting a frictional force generated during service of the laundry mangle, said mangle comprising at least one mangle roller, at least one arm for supporting said mangle roller in a heatable trough in a service position, said mangle roller and said trough being movably positioned relative to each other, inlet and outlet passages for laundry articles provided between said mangle roller and heatable trough;
- a force generating mechanism which counteracts the frictional force generated during service of the laundry mangle comprising an adjusting device acting on a component selected from the group of components consisting of said mangle roller and said trough, said adjusting device comprising a torque generating device including a rotatable rocking arm, said mangle roller having an axle operatively connected to said rocking arm for rotating said roller.
