Description

[Detailed description of the invention] [Industrial application field] This invention continuously overlaps and transports a continuous form coated with pressure-sensitive adhesive at predetermined locations, cuts and presses it, and continuously seals sealed documents. The present invention relates to a pressure-bonding, overlapping and stitching form creating device for creating a form by overlapping and stitching together materials such as the above.

[Prior art and its problems] Conventionally, in order to create sealed documents that require individual information, pressure-sensitive adhesive was applied to the envelope form in advance, the necessary information was written, and then the paper was folded. Previously, envelopes were created by stacking, cutting, stacking, or stacking other forms and applying pressure using finger pressure to adhere the pressure-sensitive adhesives to each other. If this happens, it will be difficult to write information on the envelope form, and if pressure-sensitive adhesives are used, which do not adhere without a certain amount of pressure, the adhesive will peel off easily due to the weak pressure. Not only was it inconvenient, but even if it was bonded, the pressure-sensitive adhesive would adhere in misaligned positions, wrinkles would occur, and it would be unsightly.
Under normal conditions, for example, when writing information on a form or during processing such as folding, when using a pressure-sensitive adhesive that only adheres with strong pressure without adhering, apply strong pressure to increase the bonding force. When mechanically stacking and bonding is performed using a device that has rollers for applying the adhesive, for example, if the stacked forms are successively passed between the rollers in a continuous state, slight slack or misalignment in the stacking will accumulate, resulting in stacking and bonding. The form has problems such as wrinkles and misaligned adhesion, making it difficult to continuously produce envelopes with overlapping stitching.

In addition, in a device that uses such rollers to apply strong pressure to stacked foams, if a foam gets stuck between the rollers, it will be firmly sandwiched, so it is difficult to remove the foam. It has become clear that the work requires a great deal of time and effort and is extremely inefficient.

[Problems to be solved by the invention] Therefore, in this invention, pressure-sensitive adhesives S that do not adhere during normal contact between pressure-sensitive adhesives but adhere under strong pressure, such as acrylic copolymer materials, NBR, Focusing on the use of adhesives whose main ingredients are synthetic resins such as SBR and synthetic rubber, this type of pressure-sensitive adhesive S prevents wrinkles and misalignment, and allows strong pressure to be applied in a stable state. To provide a pressure-bonding, stack-stitching form creation device that can provide a crimped, stacked-stitched form, continuously create a stacked-stitched form, and can easily remove the foam, etc., if it gets stuck between pressure rollers. It is.

[Means for Solving the Problems] The pressure-bonded overlapping stitching creating device of this invention has continuous unit forms coated with a pressure-sensitive adhesive that does not adhere during normal overlapping contact but actually adheres under a predetermined pressure. a means for superimposing continuous forms, a means for transporting continuous forms in a superposed state, a pair of upper and lower rollers rotating at approximately the same circumferential speed as the continuous form being transferred, and a pair of upper and lower rollers having a circumferential speed faster than this roller. and a cutting means adjusted to apply cutting tension by means of roller pressure necessary for tearing and capable of temporary adhesion, each pair of rollers pinching the conveyed continuous foam; and main pressure bonding means consisting of a pair of upper and lower pressure rollers that apply a pressure greater than the roller pressure of the cutting means, which is the main bonding condition, to the pressure-sensitive adhesive of the unit form, and are provided in order in the form transport direction. The above-mentioned pair of upper and lower pressure rollers is configured to include isolation means for moving at least one roller shaft of the upper and lower pair to isolate the pair of upper and lower pressure rollers.

[Function] Therefore, the continuous form is overlapped in a continuous state by the overlapping means, and
The temporary bonded state is cut into units by the cutting means, and is bonded by the strong pressure roller of the main pressure bonding means that applies strong pressure to each unit, so it is passed between the rollers that apply strong pressure in a continuous state. It does not cause problems such as wrinkles or misaligned adhesion caused by accumulation of slight sagging or misalignment of the foam, and even when the foam is tightly packed between the rollers that continuously apply strong pressure. , the form can be easily removed.
