Abstract
An apparatus and method for continuously controlling an endless belt, the belt being driven at a constant rate around at least two rollers spaced apart from each other, marking the belt while it is being driven to obtain successive marks and measuring distances between the successive marks while the belt is being driven. The rate of belt movement is changed in accordance with the distances measured.
Claims19
A method for controlling a continuous belt upon which fabrics are mounted to receive successive printings, comprising the steps of:
- driving a tensioned continuous belt at a constant rate around at least two rollers spaced apart from each other;
- marking the belt while it is being driven to obtain successive marks;
- and
- measuring distances between said successive marks while said belt is being driven.
A system for controlling a continuous belt upon which fabrics are mounted to receive successive printings, comprising:
- a frame;
- at least two rollers spaced apart from each other and rotatively disposed upon said frame;
- a continuous belt disposed rotatively around and tensioned between said rollers;
- means for driving at least one of said rollers whereby said continuous belt is rotatively driven;
- means for marking said belt to obtain successive marks while said belt is rotatively driven;
- and
- means for measuring distances between said successive marks thereon while said belt is rotatively driven.
