Description

  The present invention is an automatic wallpaper for automatically applying, on a back surface of a wallpaper (cross), a predetermined amount of a paste for adhering to a base such as a ceiling or a wall, to a wallpaper of a predetermined length. The present invention relates to an underlaying tape for wallpaper cutting used in a gluing machine and a tape for wallpaper cutting.

  Conventionally, while automatically applying glue on the back surface of such wallpaper, an automatic wallpaper adhesive configured to stick a wallpaper cutting tape composed of, for example, an underlaying tape for wallpaper cutting, a cutting tape, etc. Attached machines have been proposed.

  The wallpaper which has been pasted with such an automatic wallpaper pasting machine has a structure as shown in FIG.

  That is, as disclosed in Patent Document 1 (Japanese Patent Application Laid-Open No. 2008-274550), as shown in the plan view on the back side of the wallpaper 100 in FIG. Adhesive is applied to the back surface 102.

  Moreover, FIG. 5 and FIG. 6 show the case where the wallpaper 100 is stuck facing the wall surface 108 from the right to the left. In this case, the wallpaper cutting underlaying tape 104 is attached in the longitudinal direction to one end 102 a of the back surface 102 of the wallpaper 100 in the width direction.

  Depending on the construction worker of the wallpaper, the wallpaper 100 may be stuck from the left to the right of the wall surface 108.

  Furthermore, a cut tape 106 is attached in the longitudinal direction to the other end 102 b in the width direction of the back surface 102 of the back surface 102 of the wallpaper 100.

  In addition, when sticking the wallpaper 100 from the right to the left of the wall surface 108 as described above, the cut tape 106 is attached to one end 102 b of the back surface 102 of the wallpaper 100 in the width direction, and the other end 102 a The underlaying tape 104 for wallpaper cutting is stuck in the longitudinal direction.

  And in the case of wallpaper construction, construction of the butt | matching part (joint part) of the wallpaper 100 is performed by the process of FIG. 6, FIG. 7 (A)-(D).

  That is, for example, as shown in FIG. 6 and FIG. 7 (A), the back surface 102 which is the pasting surface of the lower (first) wallpaper 100 is attached to the wall surface 108 made of a board or the like. And the back surface 102 which is a pasting side of the wallpaper 100 of the upper side (the second piece) is stuck on the end by the side of the underlaying tape 104 for wallpaper cutting of the wallpaper 100.

  At this time, as shown in FIG. 6, the cut tape 106 of the upper (second) wallpaper 100 is disposed so as to overlap the wallpaper cutting underlaying tape 104 of the lower (first) wallpaper 100.

  Then, as shown by the dotted line A in FIG. 6 and FIG. 7 (B), using the ruler not shown separately, with the cutter 118, the wallpaper 100 on the upper side (second sheet) and the lower side (first sheet) I will cut the wallpaper 100.

  At this time, as shown in FIG. 6 and FIG. 7B, the underlaying tape 104 for cutting the wallpaper of the lower (first) wallpaper 100 exists, so the cutter blade of the cutter 118 cuts the wallpaper By cutting the surface without penetrating the underlaying tape 104, it is possible to reliably cut two wallpapers 100 and the cut tape 106 without leaving a cut.

  Moreover, the wall surface 108 which consists of a gypsum board etc. is damaged, and the opening after wallpaper construction does not occur.

  Then, after such a cutting operation is completed, as shown by the arrows in FIG. 6 and FIG. 7 (B), the cut pieces 110 of the lower (first) wallpaper 100 and the upper (two) The cut pieces 112, the underlaying tape 104 for cutting the wallpaper, and the cut tape 106 are removed.

  After that, as shown by the arrows in FIG. 7C, the glued surface of the wallpaper 100 is made so that the cut portions of the upper (second) wallpaper 100 and the lower (first) wallpaper 100 are aligned. Is attached to the wall surface 108 (adhesion).

  Then, as shown by the arrows in FIG. 7 (D), finally, the abutment portion (joint portion) 114 of the wallpaper 100 is lightly pressed by the roller 116 so that the abutment portion (joint portion) 114 of the wallpaper 100 is Finishing construction is to be carried out.

  As a result, when the butt portion (joint portion) 114 of the wallpaper 100 is finished neatly and cut by the cutter 118, for example, the wall surface 108 made of a board or the like is not damaged or the wallpaper 100 does not float. The condition is good.

JP 2008-274550 A

  By the way, as shown in the cross-sectional view of FIG. 8, as the conventional underlaying tape 200 for wallpaper cutting, for example, the base material layer 204 attached to the base 202 side such as a ceiling, wall surface etc. An uneven layer 206 is provided on the side where the uneven surface is formed.

  In this case, the concavo-convex layer 206 is formed, for example, from a concavo-convex pattern having a substantially lattice shape in plan view.

  Further, as shown in the cross-sectional view of FIG. 9, as the conventional underlaying tape 300 for wallpaper cutting, for example, a base layer 304 adhered to the base 302 side such as a ceiling or a wall surface, and an upper surface of the base layer 304 An uneven layer 306 provided on the side is formed.

  Furthermore, when peeling the underlaying tape 300 for wallpaper cutting provided on the upper surface side of the uneven layer 306 from the wallpaper, for example, the paste on the wallpaper side is not transferred to the underlaying tape 300 for wallpaper cutting. For example, the surface layer 308 is provided with embossing or the like. Also in this case, the concavo-convex layer 306 is formed of, for example, a concavo-convex concavo-convex shape in plan view.

  8 and 9 schematically show partial enlarged cross-sectional views of the conventional underlaying tapes 200 and 300 for wallpaper cutting, and the thickness of each layer is the thickness of FIGS. 8 and 9. Of course, it is not limited to the ratio of.

  However, in the conventional underlaying tapes 200 and 300, as shown in FIGS. 8 and 9, the surface on the side that contacts the wallpaper (FIGS. 8 and 9) so as not to damage the base 202 and 302 sides. The uneven layers 206 and 306 are formed on the upper surface side.

  That is, as shown in FIG. 7, when the butt portion (joint portion) 114 of the wallpaper 100 is cut by the cutter 118, the concavo-convex layers 206 and 306 directly grasp the cutter 118 by the sense of asperity to the builder of the wallpaper. It is designed to be located in the surface which a convex-concave surface touches on the wallpaper side so that it may be transmitted to the hand.

  Further, the convex portion is not easily cut by the cutter 118, and for example, a material such as a film or a thread is used.

  For this reason, when the height difference of the unevenness of the unevenness layers 206 and 306 is low, there is a possibility that the blade of the cutter 118 may fall into the recessed portion. The blade of the cutter 118 may penetrate through the wallpaper cutting underlaying tape 200, 300 at the portion where the blade of the cutter 118 falls, for example, and may cut the base 202, 302 such as a ceiling or a wall surface. .

  That is, when the foundations 202 and 302 after the wallpaper construction work are confirmed, there may be scratches as innumerable dotted lines. As a result, in such a dotted line portion, the paste on the wallpaper side is dried from the portion continuously connected as a solid line, and a floating portion is generated on the wallpaper.

  In addition, in the portion where the dotted line portions are continuously connected as a solid line, the grounds 202 and 302 are opened, and the wallpaper pasted thereon is also torn together.

  On the other hand, on the other hand, when the height difference of the unevenness of the unevenness layer 206, 306 is high, the blade of the cutter cutter 118 may not reach the recess of the unevenness layer 206, 306 as the speed of sliding the cutter 118 is faster. .

  As a result, failure to cut the wallpaper occurs, and the construction worker of the wallpaper often can not detect such failure to cut, and when removing the scrap of the wallpaper, it becomes a form to tear off the broken portion. , The appearance of the construction state of the wallpaper will be worse.

  Even if such a cutting failure can be detected by the wallpaper construction worker, the blade of the cutter 118 is again inserted into the recess (wall paper) of the uneven layer 206, 306 until the cutting failure point is broken. As a result, the appearance of the construction state of the wallpaper becomes worse.

  Furthermore, as the surface layer (concave / convex layer 206, surface layer 308) of the underlaying tape 200, 300 for wallpaper cutting is made of a hard material that can not be easily cut with the cutter 118, the cutting of the wallpaper is more likely to occur. Become.

  In order to avoid such a state, the construction worker of the wallpaper tries to press the cutter 118 consciously so that the cutting state is slightly deepened. For this reason, the blade of the cutter 118 reaches up to the base 202, 302 and cuts the base 202, 302 or conversely, cutting failure of the underlaying tape 200, 300 for wallpaper cutting occurs. It will be.

  In addition, the worker of the wallpaper has a tendency to strongly press the cutter 118 against the wall at the start and end of cutting, and the middle tends to be weak. Therefore, when the construction worker of the wallpaper cuts in a cramped posture, the strength is further increased, and the ground may be cut or cutting may occur.

  Therefore, as shown in the steps of FIG. 6 and FIGS. 7A to 7D, in the construction (joint cut by overlapping cutting of the wallpaper) of the abutment portion (joint portion) of the wallpaper 100, the wallpaper as described below Underlaying tapes for cutting are required.

  That is, there is a demand for an underlaying tape for wallpaper cutting which does not damage the ground even if the cutter blade passes through the underlaying tape for wallpaper cutting and the operator of the wallpaper construction works in a tight posture.

  Also, in order to prevent breakage of the two overlapping wallpapers, the surface layer of the underlaying tape is a soft material that is easily cut by a cutter blade, and the underlaying tape for wallpaper cutting can reliably cut the wallpaper. Is required.

  On the other hand, in the automatic wallpaper gluing machine, the wallpaper cutting tapes (the underlaying tape for wallpaper cutting 104 and the cut tape 106) are attached to the back surface 102 which is the gluing surface of the wallpaper 100 during the gluing operation by the automatic wallpaper gluing machine. In this state, since the surface side of the wallpaper 100 is discharged in a state of being located on the worker side, the tape for cutting the wallpaper can not be visually recognized from the worker.

  For this reason, it is not known that the end of the tape for wallpaper cutting (the underlaying tape for wallpaper cutting 104 and the cut tape 106) in a state of being wound in a roll shape approaches the winding tube and unrolling occurs. Even when approaching, you may not notice that the unwinding occurs.

  For example, it was often noticed for the first time that the tape for tape cutting in the form of a roll was lost for the first time due to the noise generated when the tape for tape cutting in a roll shape was peeled off from the winding tube.

  However, in this case, when the tape for cutting the wallpaper is small in noise generated when it is peeled off from the winding pipe, the noise of the surrounding work environment may be wiped out and the worker may not notice it.

  Therefore, in the conventional automatic wallpaper gluing machine, as described above, in the state where the tape for cutting the wallpaper is unwound, the wallpaper 100 for the length set by the automatic wallpaper gluing machine is the tape for cutting the wallpaper (wallpaper In a state where the underlaying tape for cutting 104 or the cut tape 106 is not attached, the gluing process is performed.

  For this reason, a paste for the wallpaper cutting tape is not stuck for the wallpaper 100 in a state of being folded below the automatic wallpaper pasting machine by finishing the pasting process and cutting (cut) the set length. It takes time and effort and time-consuming work to spread the wallpaper 100 on the floor surface etc. and manually paste the wallpaper cutting tape (the underlaying tape for wallpaper cutting 104 or the cut tape 106) manually. It will

  In particular, for example, the average length of the wallpaper 100 attached to the ceiling of 6 tatami and 8 tatami is generally about 3,640 mm, and when the portion to which the wallpaper cutting tape is not attached is long, In order to attach the tape for wallpaper cutting (the underlaying tape for wallpaper cutting 104 or the cut tape 106) by such manual work, it takes time and time, and a complicated operation is required.

  Since it is necessary to attach the tape for wallpaper cutting by hand like this, the glue adheres to the hand, and the operation to wash and wipe the hand is also required, which also contributes to a reduction in the working efficiency. ing.

  In addition, it is also necessary to replace the tape for wallpaper cutting in which unrolling has occurred with the tape for tape for wallpaper cutting (the underlaying tape for wallpaper cutting 104 or the cut tape 106) in a state of being wound into a new winding tube. It also contributes to the decline in work efficiency.

On the other hand, for example, when constructing a wallpaper on a ceiling etc., as shown in FIG. 10, it is separated from the end 402 a in the width direction of the back surface 402 of the wallpaper 400 by a fixed distance t (for example, 10 to 15 mm) It is practiced to stick a wallpaper cutting tape (a backing tape or cut tape for wallpaper cutting) 404.
Such pasting of the wallpaper cutting tape 404 is pasted by the wallpaper pasting machine at the time of pasting work by the wallpaper pasting machine.

  As a result, the adhesive surface has a fixed distance t from the end 402 a in the width direction of the back surface 402 of the wallpaper 400, and the wallpaper 400 can be temporarily fixed to the ceiling, which is convenient for wallpaper construction It is done.

However, when the adhesive surface has a fixed distance from the end in the width direction of the back surface 402 of the wallpaper 400, the adhesive surface is exposed.
For this reason, the glue is gradually dried from the end of the wallpaper 400, including the open time for blending the glue applied to the wallpaper 400, and the sticking function is lost.
As a result, it is not possible to peel off the folded wallpaper in a state in which the pasted surface is glued by the wallpaper gluing machine and the glued surface is brought into contact, and peeling occurs and the backing paper of the wallpaper 400 is torn. It will not be possible to temporarily fix the ceiling.

Furthermore, when the adhesive surface has a fixed distance from the end in the width direction of the back surface 402 of such wallpaper 400, the adhesive surface is exposed, the adhesive is dried, and the adhesion function is lost. As a result, the pasted wallpaper 400 can not be stored for a long time.
Therefore, put a sponge or towel containing moisture into a bag or case that has a storage function to prevent drying of the paste on the paste surface, and keep the water, or be careful of the wallpaper after pasting, It is inconvenient because the wallpaper 400 has to be attached early and early.

  In view of such a present condition, the present invention does not damage the groundwork even if the cutter blade passes the underlaying tape for wallpaper cutting and the construction worker of the wallpaper applies with tight posture. The purpose is to provide an underlaying tape.

  In addition, according to the present invention, the surface layer of the underlaying tape for wallpaper cutting is a soft material that can be easily cut by a cutter blade, so that it is possible to prevent breakage of two vertically stacked wallpapers, which reliably cuts the wallpaper. It is an object of the present invention to provide an underlaying tape for wallpaper cutting that can be achieved and is difficult to reach the ground.

  Moreover, the present invention can detect in advance that the end of the tape for wallpaper cutting in a state of being wound in a roll shape approaches a coiled tube and generation of unwinding occurs, and a conventional automatic wallpaper gluing machine It is an object of the present invention to provide an underlaying tape for wallpaper cutting and a tape for wallpaper cutting in which the pasting process is not performed in a state where the wallpaper cutting tape is not stuck.

  In addition, the present invention spreads the wallpaper for the portion to which the wallpaper cutting tape is not stuck straight on the floor etc. and pastes the wallpaper cutting tape manually as in the conventional automatic wallpaper gluing machine. An object of the present invention is to provide an underlaying tape for wallpaper cutting and a tape for wallpaper cutting which does not require complicated work, has a good working efficiency, and is easy to replace with a new wallpaper cutting tape.

  Furthermore, according to the present invention, when the adhesive surface has a fixed distance from the end in the width direction of the back surface of the wallpaper, for example, the wallpaper can be temporarily fixed to the ceiling, which is convenient for wallpaper construction and moreover, wallpaper Can be prevented from peeling off as much as possible from the end of the paste, peeling off can be prevented without losing the sticking function, and can be temporarily fixed to the ceiling of the wallpaper. The purpose is to provide a tape.

Hereinafter, embodiments (examples) of the present invention will be described in more detail based on the drawings.
Example 1

  FIG. 1 is a partially enlarged cross-sectional view of a wallpaper cutting underlaying tape 10 of the present invention.

  In FIG. 1, reference numeral 10 generally indicates a wallpaper cutting underlaying tape 10 of the present invention.

  The underlaying tape 10 for wallpaper cutting of the present invention is the underlaying tape 10 for wallpaper cutting used when cutting a wallpaper in wallpaper construction, as shown in FIG. 6 and FIG. 7 described above.

  As shown in FIG. 1, the wallpaper cutting underlaying tape 10 is provided with a soft surface layer 12 located on the surface side (the side on which the cutter blade abuts). The intermediate layer 14 is harder than the surface layer located on the lower surface side of the surface layer 12. Furthermore, on the lower surface side of the intermediate layer 14, for example, an uneven layer 16 is provided in which an uneven portion located on the base side such as a wall or a ceiling is formed.

  In this case, the surface layer 12 is preferably made of a flat film which is easily cut by a soft (soft) cutter blade, such as polyethylene.

  The intermediate layer 14 is preferably composed of an intermediate layer 14 harder than the surface layer 12, such as a metal layer formed by vapor deposition of a metal such as polypropylene or aluminum foil harder than polyethylene. .

  Furthermore, the concavo-convex layer 16 is preferably composed of a concavo-convex layer 16 harder than the surface layer 12, such as polypropylene harder than polyethylene, for example.

  The structure of the uneven layer 16 is not particularly limited as long as the uneven layer 16 has an uneven surface, but the wallpaper construction worker works on the construction (a joint portion) of the wallpaper by the uneven surface of the uneven layer. In joint cutting by overlapping and cutting the wallpaper, it is possible to transmit the vibration to the cutter blade to the wallpaper construction worker, and the wallpaper construction work delicately controls the force change sensibly by the vibration. It is desirable that it is a structure that can be cut reliably without cutting the wallpaper.

  As such a concavo-convex layer 16, for example, it is desirable that the concavo-convex layer 16 be formed from a concavo-convex concavo-convex shape in plan view.

  Furthermore, in this case, the ratio of the hardness of the surface layer 12, the intermediate layer 14, and the concavo-convex layer 16 is not particularly limited, but in consideration of the effect of cutting the wallpaper described later, the surface layer 12 and The hardness ratio of the intermediate layer 14 to the uneven layer 16 is, for example, about 1.5 times the hardness of the intermediate layer 14 and the uneven layer 16 with respect to the hardness of the surface layer 12. It is desirable to

  In this case, the ratio of the thickness of the surface layer 12, the intermediate layer 14, and the concavo-convex layer 16 may be appropriately selected according to the material of the surface layer 12, the intermediate layer 14, and the concavo-convex layer 16. It is not particularly limited.

  In this case, for example, the thickness of the surface layer 12 is 0.04 mm, the thickness of the intermediate layer 14 is 0.04 mm, and the thickness of the uneven layer 16 is 0.18 mm, in consideration of the effect of cutting the wallpaper described later. It is desirable to do.

Of course, the thickness of each of the above layers is not limited to the thickness described here.
Further, the thickness of the underlaying tape 10 for wallpaper cutting is not particularly limited, but a thinner one is more preferable, for example, the thickness of the underlaying tape 10 for wallpaper cutting is about 0.1 to 0.4 mm It is desirable to keep.

  Furthermore, as shown in FIG. 1, the distance between the concavities and convexities of the concavo-convex surface of the concavo-convex layer 16 may be a predetermined uniform spacing or a non-uniform (random) spacing.

Further, as shown in FIG. 11, the second uneven layer 18 is provided below the uneven layer 16 (on the base side) so as to provide another uneven arrangement of the uneven layer 16 in the reverse direction. It is good.
The distance between the concavities and convexities of the concavo-convex surface of the second concavo-convex layer 18 may be a predetermined uniform spacing or a non-uniform (random) spacing, as shown in FIG.

  Also in this case, the thickness ratio of the surface layer 12, the intermediate layer 14, the concavo-convex layer 16, and the second concavo-convex layer 18 is the same as that of the surface layer 12, the intermediate layer 14, the concavo-convex layer 16, the second It may be suitably selected according to the material of the uneven layer 18, and is not particularly limited.

  In this case, for example, the thickness of the surface layer 12 is 0.04 mm, the thickness of the intermediate layer 14 is 0.04 mm, and the thickness of the uneven layer 16 is 0.1 mm, in consideration of the effect of cutting the wallpaper described later. It is desirable that the thickness of the second uneven layer 18 be 0.1 mm.

  In this case, although the two concavo-convex layers of the concavo-convex layer 16 and the second concavo-convex layer 18 are provided, it is of course possible to provide a plurality of three or more concavo-convex layers.

  1 and 11 schematically show a partially enlarged cross-sectional view of the underlaying tape 10 for wallpaper cutting of the present invention, and the thickness of each layer is the thickness of FIGS. 1 and 11. Of course, it is not limited to the ratio.

  By configuring in this manner, the soft surface layer 12 located on the surface side can be cut with a continuous solid line by a cutter, and cutting can be performed reliably without cutting the wallpaper.

  Moreover, since the intermediate layer 14 harder than the surface layer 12 is positioned on the lower surface side of the surface layer 12, the hard intermediate layer 14 physically prevents the cutter blade from continuously reaching the base to some extent. be able to.

  Furthermore, since the uneven layer 16 is formed on the lower surface side of the intermediate layer 14 with the uneven layer 16 located on the base side such as a wall or a ceiling, the wallpaper construction operator When performing construction (joint cutting) of a part (joint part), vibration can be transmitted to the cutter blade to the wallpaper worker, and the wallpaing work can be performed sensibly by the vibration. You can control the amount of force delicately, you can cut it without failure to cut the wallpaper.

  In addition, the cutter blade reaches the ground by the physical thickness of the three-layer structure of the surface layer 12, the intermediate layer 14 harder than the surface layer 12, and the uneven layer 16 in which the unevenness located on the lower side is formed. Can be prevented. As a result, since a continuous cut on the base is difficult to occur, it is difficult for the opening to occur and the appearance of the wallpaper construction is improved.

  Therefore, it is possible to provide the underlaying tape for wallpaper cutting which does not damage the ground even if the cutter blade passes through the underlaying tape 10 for wallpaper cutting and the construction operator of the wallpaper applies with tight posture. it can.

In addition, the surface layer 12 of the underlaying tape 10 for wallpaper cutting is a soft material that can be easily cut by a cutter blade, so that it is possible to prevent cutting of two overlapping wallpapers, and it is possible to reliably cut the wallpaper. An underlaying tape 10 for cutting the wallpaper can be provided.
