Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for making a folding card, and more specifically, the present invention relates to a method for producing a folded card, and more specifically, it is applied to a printed continuous card sheet in the middle of folding in the form of minute droplets using an adhesive application means to remove wrinkles. The present invention relates to a method for overlapping folding cards in the production of folding cards, which is characterized in that the folding cards can be easily folded without causing any damage.

Conventionally, folding cards have been produced by stacking continuous card sheets with a pressure-sensitive or rewetting adhesive pre-applied to the back side of the continuous card sheet before information is printed out.

However, continuous card sheets coated with pressure-sensitive adhesives are prone to blocking problems due to temperature, humidity, and load during transportation or storage before sealing, and if you want to print using an electrostatic printer, Since the toner print is fixed using a heating method, the pressure-sensitive adhesive softens and causes trouble, so it could not be used in electrostatic printers.

Continuous card paper sheets using rewetting adhesives were also undesirable due to high humidity blocking.

Also, it has been proposed to print out the necessary information on continuous card sheets and then apply adhesive without applying adhesive in advance, but when using liquid adhesive, , the continuous card paper absorbs moisture from the adhesive, causing the paper to stretch and become soft, making it difficult to fold. Also, since wrinkles occur during folding, a quick-drying pressure-sensitive adhesive is used, and after drying, the paper is folded, heated, or pressed. However, another method is to print out the necessary information on a continuous card and then apply electrostatic powder adhesive using an electrostatic method. Although this method has been proposed, it has drawbacks such as an expensive adhesive application device.

Therefore, in this invention, adhesive can be applied without any problems even when the paper used for continuous cards is thin and has good moisture absorption when creating folded cards.
To provide a method for overlapping folding cards which can be folded without causing wrinkles and can be produced at low cost.

Next, to explain this invention in detail, FIG. 1 shows a continuous card paper sheet 1 from which a folded card is made. A large number of card sheets 3 are formed by connecting two pieces of paper, a piece of paper A and a piece of paper B on the lower side, in the direction in which the pieces of paper are connected, and a continuous card is formed along both sides of the two pieces of paper A and B in the longitudinal direction of the connection. A transfer hole section 4' having transfer holes 4 useful for transferring the sheet 1 is provided.

In addition, on the surface of each card sheet 3, paper strip A has an address section 5 as a postcard specification, and paper strip B has a notification section 6.
However, the back side is not provided with any adhesive like the conventional continuous card paper sheet.

Note that 2' is a perforated folding perforation which is a line of weakness for folding provided along the folding portion 2, and 7 is a cutting perforation for dividing and cutting each card sheet.

In order to create a folded card according to the present invention from the above-mentioned continuous card paper sheet 1, necessary information is printed in the address section 5 and notification section 6 of each card paper sheet 3 of the continuous card paper sheet 1 using an electrostatic printer. After the continuous card sheet 1 is transferred, a small amount of adhesive is applied to the back side of the paper piece A or paper piece B while the back sides are polymerized from the rising edge of folding along the folding perforation 2'. Apply it as a droplet, then polymerize and adhere the back sides sequentially from the side closest to the folding perforation 2' to the side farthest from the folding perforation 2', and cut out each unit of card paper that has been folded and glued one after another. This invention will be explained using a folding device 10 which is used to create a folded card by separating it from the perforation 7, and which is shown in FIG.

The folding device 10 shown in FIG. 2 is provided in a direction perpendicular to the longitudinal direction of the continuous card paper sheets 1, and holds the card paper sheets 3 in a substantially flat state in this direction. In order to fold the continuous card paper sheet 1 along the line of weakness while pulling the continuous card sheet 1 in a substantially vertical direction from the support member 11, A receiving member 9 is provided which is substantially orthogonal to the supporting member 11, and an adhesive spray nozzle is provided as an adhesive application means located in front of this receiving member 9 and facing approximately the center of the back surface of the paper piece A near the rising edge of the folding. 12, and further, in an intermediate process between the support member 11 and the receiving member 9, the folded card sheet 1 coated with adhesive is folded so that the side closer to the fold perforation 2' of the card sheet 3 is lower, and the fold perforation is lower. The side far from 2', that is, the transfer hole 4' side, is highly oblique, and the sandwiching members 13, 13, which are composed of two bars that sandwich the front side of the two connected paper pieces in the middle of folding, and the paper piece B side and the paper piece A side Auxiliary bars 14a and 14b apply appropriate tension to the continuous card sheets 1 being folded, and a tractor 15 applies conveying force to the continuous card sheets 1.
and a slitter 16 for cutting out the transfer hole 4', low-speed rollers 17, 17, blade 18, and high-speed roller 1.
It consists of a cutting device 20 consisting of 9 and 19, and a suction device 21 which sucks up minute droplets of adhesive that are sprayed onto the continuous card sheet, reflected toward the front, and not applied on the edge side.

The adhesive injection nozzle 12 has an adhesive pressure-feeding pipe 12a that pumps the liquid adhesive G, and a function that controls the adhesive inside the adhesive pressure-feeding pipe 12a at the nozzle tip side when the tractor 15 is started and stopped. It consists of control pipes 12b, 12b for opening and closing, and a pneumatic feed pipe 12c that applies air pressure to the liquid adhesive G that has been pressure-fed to the nozzle tip and turns it into minute droplets.

After printing out the necessary information on the aforementioned continuous card sheet 1 using an electrostatic printer, it is placed parallel to the support member 11 of the folding device 10 as shown in FIG. between the auxiliary bar 14a and the clamping members 13, 13, which raise the continuous card paper 1, overlap the back sides of the paper strip A and the paper strip B, and apply tension from the paper strip B side to the front, and After passing under the auxiliary bar 14b and inserting the transport holes 4 of the folded continuous card paper sheets 1 into the transport holes 4' and 4' into the tractor 15, and setting the continuous card paper sheets 1 on the folding device 10, the tractor 15 start.

With the start of the tractor 15, the folded continuous card sheet 1 is transferred, and at the same time as this transfer, the valve of the adhesive injection nozzle 12 is opened by the control tubes 12b, 12b, and the adhesive is force-fed from the adhesive pressure feeding tube 12a. The liquid adhesive G is turned into minute droplets by the air pressure of the pneumatic feed pipe 12c, and is applied to approximately the right half of the back surface of the paper piece A, as shown in the unfolded state in FIG.

Next, the back sides of the pieces of paper A and B are held together by the sandwiching member 1.
Since the folding perforations 2' side of No. 3 and 13 are provided in a low and oblique manner, the back sides of paper pieces A and paper pieces B on the side closer to the folding perforation 2' overlap, and then the continuous card paper sheets 1 Fold perforation 2' due to transportation
The back surfaces on the far side, that is, on the side of the transfer hole 4' are polymerized, and these overlapping surfaces are adhered by the liquid adhesive G made of the minute droplets, and then the transfer hole 4' is slitted by the slitter 16. Tension is applied by low-speed rollers 17, 17 and high-speed rollers 19, 19, and at the same time, the cutting perforation 7 comes into contact with the blade 18, and the card is separated and a folded card 22 is created.

In the above, the adhesive spray nozzle provided as the adhesive application means may be provided on the back side of the paper piece B, and the sandwiching members 13, 13 may be placed on the side far from the folded part of the continuous card paper sheet 1. Other forms may be used as long as the back sides are folded in an orderly manner.

Therefore, according to this invention, since the adhesive is applied from the start of folding of the continuous card sheet to the process of being folded by the receiving member, the preparation for folding is already completed before and after that, and furthermore, the preparation for folding is already completed before and after the folding by the holding member. Two consecutive pieces of paper are sandwiched diagonally with a paper sheet, and as the continuous card paper sheets are conveyed, the back sides from the side closest to the folding part to the side farthest from the folding part are sequentially overlapped and glued, so that wrinkles and slack escape to the side farthest from the folding part, and the card width Even if the cards are wide, folded cards can be easily overlapped without causing wrinkles, sagging, or air bubbles, so you can write notifications and record items on both the front and back using a non-impact printer or impact printer that can only print on one side. You can easily create postcards, membership cards, ledgers, notification cards, etc. that require
