The present invention relates to a corner rounding machine for a printed matter, and more particularly, to a corner rounding machine for use in a corner rounding cutting operation of various types of paper prints, in which a plurality of printed matters are effectively arranged and arranged, The present invention relates to a printed article corner rounding machine that significantly improves quality and provides a safe working environment.

Generally, printed materials such as various business cards or promotional luggage papers are subjected to a process of cutting and cutting the printed material according to the target standard or form.

BACKGROUND ART [0002] Conventionally, a cutter used for cutting a printed product is a device configured to cut a printed matter collectively outputted on a large paper in a predetermined interval and a size in a longitudinal direction and a width direction, and there are manual and electric cutters of various sizes.

For example, a business card site cutting device is known from Registration Practical Utility Model No. 20-0264570. In the construction of the business card site cutting device, a guide portion and a power switch, which are integrally formed with the longitudinal cut portion and the width cut portion of the card business card, And the cutting portion is provided with a saw-like cutting blade which is engaged between the entry roller and the entry roller, so that the business card is cut longitudinally and laterally.

The rolling cutting method in which the cutting blade is rotated and cut on a printed material as in the prior art has a disadvantage in that it is not easy to cut a relatively large amount of printed material at one time because the printing material is inevitably jammed.

As a further prior art of the present invention, in a configuration of a name card manufacturing apparatus of the registered utility model No. 20 - 0344247, a name plate placed on the upper surface of the base frame is seated on the upper surface thereof, A lift frame which is vertically raised and lowered through guides of a guide bar provided on the upper side so as to correspond to the jig frame, A punching frame provided on a bottom portion of the base frame and arranged to project a plurality of punching members downward so as to cut the business card when the base is lowered on the bottom portion thereof; So that a larger amount of printed matter can be cut in a punching manner Respectively.

Meanwhile, in recent years, designs have been diversified according to the use of the printed matter. In particular, there has been a great increase in the demand for printed materials having a sophisticated design with a curved shape deviating from the straight shape of the past. Especially, business cards and sticky promotional materials are more sensitive to the abrasion rate of the printed corner than the general office work or the handbag because of their more demanding handling and storage properties, so they tend to prefer curved corners to straight corners.

Reflecting this reality, there is provided a technique for cutting a corner of a printed product into a curved shape by using a blade used in a punching-type cutting apparatus to which the above-described conventional technology is applied in the form of a curved corner .

Registration Utility Model No. 20 - 0264570 Registration Utility Model No. 20 - 0344247 Registered Utility Model No. 20 - 0283613 Registration No. 10 - 1261017
