Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of continuously gluing and cutting cellophane to the window of a windowed envelope.

In the conventional method, glue was applied around the window of the base paper for windows, and cut pieces of cellophane tape were pressed and adhered to the tree, but with this method, if the timing of the window and the cellophane tape was misaligned, the window There is a disadvantage that the base paper adheres to the pressure roll etc., and the work must be interrupted.

The present invention has been made in order to eliminate such drawbacks, and it also makes it possible to quickly and efficiently apply cellophane tape to the window of a windowed envelope, as well as cutting, transferring, and attaching in a continuous process. It is an object of the present invention to provide a method that can be performed easily and reliably, thereby providing a single step suitable for fully automatic manufacturing of window envelopes.

The following five inventions will be explained in more detail.

The feature of the present invention is that after gluing the cellophane tape to the shape of the window of the base paper with a window and at intervals that match the window, the cut space between the glue is cut, and the cut cellophane tape piece is attached to the window. Attachment 1 Continuously glue cellophane to the cavity of the windowed envelope, which is characterized by continuously adhering to the window of the paper.
There are methods of XJ cutting and cutting and gluing.

Next, the apparatus used in the present invention will be explained with reference to the drawings.

In the figure, 1 is a tape winding, 2 is a feed roll, the cellophane tape S is fed out from the tape winding 1, and the cellophane tape is transferred at a constant feed rate. FIG. 7 shows the state of the cellophane tape S at this stage, that is, the state at position SA in FIG. 4, and in this state, no glue has been applied to any extent. 3 is a roll in which the glue is applied from the glue tank 4 through rolls 5a and 5b to its circumferential surface, and this glue is applied at equal intervals to the cellophane tape S that is being continuously transported. . Further, the size material is provided with a protrusion 3a on the circumferential surface of the roll 3, which matches the shape of the window of the windowed base paper. Figure 8 shows the state of the cellophane tape S at this stage, that is, the state of the position SB in the upper part of Figure 4. is coated on. Reference numeral 6 denotes a stand roll that comes into rotational contact with the gluing roll 3. Reference numeral 7 denotes a cutting adhesive drano, and a blade holder 9 that is disposed inside the suction drum and holds the blade 8.
The diameter is the same as the circumferential diameter of the cutting edge of the receiving blade 8 when it rotates, and an appropriate vacuum hole (not shown) is applied to the outer circumferential surface. When a required number of suction holes 10 are provided connected to the suction drum 12, the suction drum 12 is provided with a notch 11 through which the cutting edge of the receiving blade 8 enters and exits, and is moved at the same speed as the feeding speed of the base paper P. rotates at a constant speed,
In addition, the blade holder 9 and the suction drum 12 are attached to a double-structured rotating shaft 13 and 14 whose axes are slightly shifted in the horizontal direction.
are fixed to each other. The rotary shafts 13 and 14 are constructed as shown in Fig. 6.

The rotating shafts 5.3 and 1.4 are cylindrical rotating shafts that are divided into two parts on both sides of the round bar-shaped rotating shaft 13 excluding the center in the axial direction, and the two parts rotate integrally. Install the shaft 14
, 1, - The rotating shaft 14 is caused to rotate separately from the rotating shaft 13, and the rotational force of the rotating shaft 130 is further transmitted to the rotating shaft 14 through a transmission mechanism such as a gear, The receiving blade holder 9 is fixed to the axial center of the rotating shaft 13 as described above, and the suction drum 12 is attached to the rotating shaft J4 as a suction drum boulder 12'.

Two sets of retaining blades 8, which are fixed via 12', are provided in opposite directions. Reference numeral 15 indicates that the cutting edge of the receiving blade 8 on the rotating circumference of the cutting and adhesive drum 7 is connected to the suction drum 12.
This is a cutter blade which is disposed at a position protruding from the notch 11 of the cutter blade, the cutting edge of which comes into contact with the cutting edge of the receiving blade 8, and is fixed to the machine body with a holder 16. By contact between the receiving blade 8 and the cutter blade 15, the gap between the glues of the cellophane tape S interposed between the cutting adhesive drape 7 and the cutter blade 15 is cut. Additionally, the cutting and adhesion drum 7 is configured such that its receiving blade 8 protrudes from the insertion part 11 of the suction drum 12 between the adhesives of the cellophane tape. Reference numeral 17 denotes a comb roll which is arranged at a required distance in the rotational direction of the cutting and adhesive drum 7 from the cutter blade 15 that falls on the rotational circumference of the cutting and adhesive drum 7 and comes into rotational contact with the cutting and adhesive drum 7. . FIG. 9 shows the state in which the cutter blade 15 cuts the glue and the suction hole IO of the suction drum 12 suctions Jl and displaces the glue, that is, the state at the position SC in the upper part of FIG. 4. It is cut out from the center and separated into individual pieces. It's snowing, etc. The P on the diagram is the original paper with a window, prl' 4 Figure IP

The piece of cellophane cheese is pasted on.

Therefore, according to the present invention as described above, since the glue is applied to the side of the cellophane tape to be adhered to the window of the base paper with a window, the timing of the window and the cellophane tape piece is misaligned. However, unlike the conventional case, the mismatch of 1r11 does not occur. Also, put cellophane on the window of the envelope.
Gluing is carried out quickly and efficiently by continuous processes including cutting, transferring, and gluing.

This method can also be carried out reliably, which makes it possible to obtain a method suitable for fully automatic manufacturing of envelopes with windows.
