Abstract

PURPOSE:To manufacture an easily recyclable booklet without making use of a stitcher, by a method wherein after a plurality of pieces of rotary printing paper are starched mutually linearly at the central part in the widthwise direction, they are folded into two at the central part by plow folding and cut into fixed sizes in order in a top and bottom directions. CONSTITUTION:In the case where a booklet A which is in size A4 and has 8 pages is manufactured, though two pieces of rotary printing paper 7, 8 wherein one color or a large number of color printing is performed beforehand and their width is in size A3 are allowed to gather by piling upon each other in a gathering part 3, on this occasion, the central part of the lower side rotary printing paper 8 is starched linearly by a starching part 2 provided on the upstream side of the gathering part 3. Two pieces of the rotary printing paper 7, 8 piled upon each other on the gathering part 3 are advanced to a longitudinal folding part 4 under being starched at their central part and after they are folded into two by plow folding hereupon, they are advanced to a sheet cutting part 5. At the time of the plow folding, the starching part is bent and pressure- contacted by a bending plow holder 4a. A sheet after cutting is accumulated to a pile stucker part 6.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing booklets such as publications, travel guides, product introductions, and other pamphlets of various standard sizes.

[0002]

2. Description of the Related Art The above booklet is manufactured by a process of stacking a plurality of rotary printing papers, binding the folded portions with a stitcher, folding them, and cutting them into a predetermined size.

[0003]

Recently, recycling of paper has been required due to environmental problems and the like. However, in the conventional manufacturing method, binding is performed by binding the folded portion with a stitcher. The booklets produced could not be recycled without removing all stitchers from each booklet. Therefore, the cost of recycling the booklet manufactured by the conventional manufacturing method is high.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method of manufacturing a booklet that can be manufactured without using a stitcher and can be easily recycled.

[0005]

In order to achieve the above object, a method for manufacturing a booklet according to the present invention is such that a plurality of rotary printing papers 7 and 8 are glued to each other linearly at a central portion in a width direction, Then, the glued central portion is folded in two by plow folding and sequentially cut into a predetermined size in the vertical direction.

[0006]

[Operation] The folded part of the two folds is bound by gluing.

[0007]

EXAMPLES Examples of the present invention will be described below. In the figure, 1 is a booklet making machine, which has a gluing section 2, a collecting section 3, a vertical folding section 4, a sheet cutter section 5, and a pile stacker section 6. Using this booklet making machine 1, A4
A method for making a size, 8-page booklet A is described below.

Two rotary papers 7 and 8 each having a width of A3 size (420 mm) are superposed and collected at the collecting unit 3.
At this time, the gluing unit 2 provided on the upstream side of the collecting unit 2 linearly glues the central portion of the rotary paper 8 on the lower side. The two rotary papers 7 and 8 are those which have been subjected to one-color or multi-color printing in advance by another printing machine or in a printing section installed upstream of the gluing section 2. This printing is performed on both the front and back sides of each rotary printing paper or on one side.

The two rotary web sheets 6 and 7 superposed in the collecting section 3 proceed to the vertical folding section 4 while being glued at the central portion thereof, where they are plow-folded to have a width of 210 mm and a sheet cutting section. Go to 5. At the time of this plow folding, the gluing portion is bent, and the plow holder 4a for bending at this time press-bonds it.

Next, the sheet cutter unit 5 travels (top and bottom).
The piles 6 are sequentially cut to have a directional dimension of 297 mm and are piled in the pile stacker unit 6. The sheet cutter 5 cuts 1
It may be cut by one blade, or may be cut by a so-called dopp drop, in which one of the up and down directions is cut into a strip shape by two blades which are arranged on the cutter drum with a slight distance in the up and down direction.

In the case of dripping off, a strip-shaped cutting piece is generated as described above, and this cutting piece is sucked and removed by the suction device 9 provided on the upper side of the cutter drum. In FIG. 1, 10 is a controller and 11 is a control panel.

[0012]

According to the present invention, the booklet A can be manufactured without using a stitcher, and the booklet which can be easily recycled can be manufactured.
