ABSTRACT:
A method of obtaining a translatory movement between two mutually contacting bodies. A wave formation is caused to move along one active portion of at least one of the bodies, which active portion is in contact with the other body. The wave formation either causes an interruption in the contact between the bodies and separates two parts of the active portion which is in contact with the other body, or forms a contact between the bodies and separates two parts of the active portion which are not in contact with the other body. The distance between two arbitrarily selected points of respective pairs of the separated parts measured along the surface of the active portion will then be longer than the shortest distance between the same points. An arrangement using the method for obtaining a translatory movement of one body relative to another with which it is in contact is also described.
