Abstract
A guiding apparatus and method for a shift generated by a web during web transportation is provided, in which a coarse position guiding module and a fine position guiding module function to directly adjust the web so as to compensate the shift occurred during the process of transportation according to a position of the web. By means of monitoring a location of the fine position guiding module at any time, a reference of the coarse position guiding module will be adjusted when the location of the fine position guiding module satisfies the condition defined in the guiding method, so as to change a position where the web enters into the fine position guiding module.
