Abstract
Apparatus for providing linear motion to a generally flat flexible material, comprising: (a) at least one piezoelectric ceramic motor situated on a first side of the flat flexible material and having a contact surface which contacts the flat flexible material and which imparts said linear motion; and (b) a bearing surface situated on a second side of the flat flexible material opposite said contact surface.

Apparatus for providing linear motion to a generally flat flexible material, comprising:
- (a) at least one linear piezoelectric ceramic motor situated on a first side of the flat flexible material and comprising a piezoelectric vibrator having an exclusive contact surface attached thereto which contacts the flat flexible material and imparts said linear motion and wherein a substantially same region of the contact surface contacts the material whenever the motor imparts motion to the material;
- and
- (b) a bearing surface situated opposite said contact surface on a second side of the flat flexible material,
- wherein the bearing surface is a contact surface of a second piezoelectric motor and wherein the second piezoelectric motor also imparts said linear motion to the flat flexible material via said contact surface of said second piezoelectric motor.
Apparatus for providing linear motion to a generally flat flexible material, comprising:
- (a) at least one linear piezoelectric ceramic motor situated on a first side of the flat flexible material and having a contact surface attached thereto which contacts the flat flexible material and imparts said linear motion and also having a second contact surface which contacts and is operative to apply linear motion to a second portion of the flexible material and wherein the linear motion imparted by the contact surface and the second contact surface are anti-parallel;
- (b) a bearing surface situated opposite said contact surface on a second side of the flat flexible material;
- and
- (c) a second bearing surface situated opposite said second contact surface on a second side of the flat flexible material.
A method for providing linear motion to a generally flat flexible material, comprising:
- (a) contacting a contact surface of at least one linear piezoelectric ceramic motor with a first side of the flat flexible material, said contact surface being attached to a single piezoelectric vibrator comprised in the linear motor so that the surface imparts linear motion to portions of the material which are in contact therewith and wherein a substantially same region of the contact surface contacts the material whenever the motor imparts motion to the material;
- and
- (b) providing a bearing surface situated opposite said contact surface on a second side of the flat flexible material,
- wherein the bearing surface is a contact surface of a second linear piezoelectric motor and wherein the second piezoelectric motor also imparts said linear motion to the flat flexible material.
A method for providing linear motion to a generally flat flexible material, comprising:
- (a) contacting a contact surface of at least one linear piezoelectric ceramic motor with a first side of the flat flexible material, said contact surface being attached to the linear motor such that the surface imparts linear motion to portions of the material which are in contact therewith;
- and
- (b) providing a bearing surface situated opposite said contact surface on a second side of the flat flexible material;
- (c) contacting a second contact surface of the at least one ceramic piezoelectric motor with one side of the flat flexible material, said motor being operative to impart linear motion to a second portion of the material which is in contact with the second contact surface and wherein the linear motion imparted by the contact surface and the second contact surface are anti-parallel;
- and
- (d) providing a second bearing surface situated opposite said second contact surface on another side of the flat flexible material.
