On the other hand, the manufactured glass substrate is loaded on a pallet for transport, storage, etc., to prevent direct contact between the glass substrates, and for stable loading, storage, and transport, interleaving paper, that is, paper is used.

Conventionally, when loading a manufactured glass substrate on a pallet, etc., the paper is supplied by releasing the paper from the paper roller, cutting it to a predetermined length, and overlapping the transferred glass substrate so that the paper is positioned between the loaded glass substrates.

On the other hand, the paper should be supplied by cutting it to a predetermined length corresponding to the size of the glass substrate.

However, when the paper wound on the paper roll is supplied, there is a problem in that the length according to the rotation amount of the paper roll is changed according to the amount of paper used.

In addition, the paper is cut by pulling the paper from the paper roll to a desired length, but there is a problem in that the length is changed after cutting due to the tension acting on the paper.

Therefore, there is a need to develop an apparatus capable of measuring the length of the cut paper by automatically taking out the paper from the paper roll and cutting it.
