Embodiment Construction

[0028] Embodiments of the present invention will be described below with reference to the drawings.

[0029] figure 1 An example of use of the flexographic printing apparatus of the present invention is shown. In the figure, 100 denotes a flexographic printing apparatus, 1 denotes a feeding unit for feeding out the elongated film F, and 2 denotes a winding unit for winding the printed film F. In FIG. The elongated film F wound on the original film roll (original reel) is installed on the discharge part 1 . This flexographic printing apparatus 100 is one form of a label manufacturing apparatus for manufacturing a shrink label to be attached to the main body of a container such as a PET bottle from the film F. This film F is a uniaxial stretching process based on polyester films such as polyethylene terephthalate and polybutylene terephthalate for shrink labels, and polyolefin films such as polyethylene and polypropylene. heat shrinkable film.

Abstract

The present invention provides a flexographic printing device with good versatility which is characterized in that: the flexographic printing device is provided with a first printing part(3)and a second printing part(4); one or not less than two printing units for flexographic printing are provided around the rotary drum conveying an elongated film by winding; a first conveying path conveying the film so as to wind one face of the film around the surface of the rotary drum of a first printing part or the rotary drum of the second printing part and thereafter wind the other face of the film around the surface of the rotary drum of the second printing part or the rotary drum of the first printing part, so as to print at both surfaces of the film; and a second conveying path conveying the film so as to wind one face of the film around each of the surfaces of the rotary drum of the first printing part and the rotary drum of the second printing part, so as to print on the single surface of the film; and the rotary drum of either one of the printing part of the first printing part and the second printing part is forwardly and rearward rotatably arranged.

Description

technical field [0001] The present invention relates to a flexographic printing device and a flexographic printing method. In detail, it relates to a flexographic printing device and a flexographic printing method with excellent versatility. Printing is performed with side recognition. Background technique [0002] In the past, a belt-shaped waist bag made of a plastic film printed with a product name, a photo, a pattern, etc. was rolled or attached to the outer peripheral surface of a container such as a polyethylene terephthalate (Petutebolt for short: PET) bottle. Labels, or shrink labels made of heat-shrinkable film, to decorate containers. Conventional shrink labels of this type have the problem of not being able to effectively utilize the other side of the film. This is because conventional shrink labels are only printed on one side of the film using a gravure printing machine. [0003] The inventors of the present invention focused on this problem earlier, and prop...
