Herein, if the binding power of the binding power specific adhesion layer A of bonding coat B is large, then, when to be fitted in by laminating film 1 on handrail and to start handrail and start to clean, laminating film 1 floats from handrail sometimes.If laminating film 1 floats from handrail, then laminating film 1 is peeled off from handrail sometimes, is wound in deflector roll.
In order to prevent it from occurring, with regard to laminating film 1, as shown in Figure 2, under the state fitting in handrail R surface, the region 13 becoming film end in bonding coat A, is endowed the binding power larger than other region.By improving the binding power becoming the region 13 of film end, thus can prevent from being peeled off from handrail R by the laminating film 1 of fitting and eliminating the winding to deflector roll.Should illustrate, Fig. 2 is the schematic perspective view of the laminating film 1 fitting in handrail R surface, can see bonding coat B from above, bonding coat A be bonded to handrail R surface and below being positioned at.
By the region 13 utilizing the adhesives with the binding power larger than other region to form bonding coat A, thus the binding power larger than other region can be given.Or, utilize and to be inserted in laminating film end and to fit in double-faced adhesive tape between laminating film 1 and handrail R surface, be bonded to the single-sided adhesive tape in the region comprising on film end and on handrail R surface, also can give the binding power larger than other region.
Utilize the adhesives with the binding power larger than other region shown in Fig. 3 and be formed with the laminating film 1 in the region 13 of bonding coat A.To the figure shows the stacked peeling paper through double treatment of bonding coat B as separate layer 2, make bonding coat A be inner side, to core 3 multilayer of cylindrical shape be wound into roll state under laminating film 1.
The adhesives forming the region 13 of bonding coat A is identical with bonding coat B with other region of bonding coat A, can be such as acrylic adhesive, elastomeric adhesive, butyl system adhesives, silicone-based adhesive, polyurethane series adhesives etc., but make the binding power of the adhesives of forming region 13 large relative to the adhesives in other region forming bonding coat A.And then, more preferably make the binding power of the adhesives of forming region 13 relative to the adhesives forming bonding coat B for more than equal.
By improving the binding power becoming the region 13 of film end, can prevent from being peeled off from handrail by the laminating film of fitting and eliminating the winding to deflector roll.In addition, owing to only improving the binding power of the subregion of bonding coat A, so remain at the paste of surface of handrail when film can be suppressed to peel off.And then, by making the binding power in region 13 be more than the binding power of bonding coat B, thus can prevent laminating film from floating from handrail.
To the peeling paper being laminated in bonding coat B as separate layer 2, preferably form mark 21 every specified length, make 2 regions 13 be set to clamp this mark 21.By with mark 21 cut-outs must length laminating film 1 and be attached at handrail, thus region 13 can reliably be positioned at film end.Should illustrate, the line, figure, perforation etc. of mark during the cut-out laminating films 1 such as mark 21 replaceable one-tenth scissors, cutter and so on.
Be provided with in laminating film end shown in Fig. 4 and be inserted into and fit in the laminating film 1 of the double-faced adhesive tape between laminating film and surface of handrail.
After the double-faced adhesive tape represented by symbol 131 is attached at the end of laminating film 1, be attached at handrail R surface together with laminating film 1.Or, after laminating film 1 being attached at handrail R surface, the end of laminating film is peeled off, by double-faced adhesive tape 131 to sandwich the part that laminating film 1 and the mode of handrail R insert stripping.In the end of laminating film 1, double-faced adhesive tape 131 becomes the state be clamped between laminating film 1 and handrail R surface.
Double-faced adhesive tape 131 is made up of base material and the bonding coat being laminated in its two sides, can possess separate layer as required.In addition, the material of base material, the adhesives forming bonding coat can be identical with base material 11, bonding coat A, B, but make the binding power of the adhesives of formation bonding coat large relative to the adhesives forming bonding coat A.And then, more preferably make the binding power of the adhesives of the bonding coat of formation double-faced adhesive tape 131 relative to the adhesives forming bonding coat B for more than equal.
By the region of the end at formation laminating film, between itself and surface of handrail, inserting the double-faced adhesive tape 131 with high adhesion, can preventing the laminating film by fitting from peeling off from handrail, thus eliminate the winding to deflector roll.In addition, owing to not needing the binding power itself improving bonding coat A, so the paste of surface of handrail remains when film can be suppressed to peel off.And then, by making the binding power of double-faced adhesive tape 131 be more than the binding power of bonding coat B, thus can prevent laminating film from floating from handrail.
The width w of double-faced adhesive tape 131 is preferably more than 5mm.By making width w be more than 5mm, thus can reliably prevent the laminating film 1 by fitting from peeling off from handrail R further.The length of double-faced adhesive tape 131 is roughly the same or slightly short to the attaching width of surface of handrail with laminating film 1.
The laminating film 1 being bonded to the single-sided adhesive tape comprising on laminating film end and on surface of handrail is provided with shown in Fig. 5.
The single-sided adhesive tape represented by symbol 132, after the attaching of laminating film 1, in film end, is attached at the region across a part for laminating film 1 and a part for surface of handrail.
Single-sided adhesive tape 132 is made up of base material and the bonding coat being laminated in its one side, can possess separate layer as required.In addition, base material material, form bonding coat adhesives can be identical with base material 11, bonding coat A, B.Preferably make the binding power of the adhesives of formation bonding coat large relative to the adhesives forming bonding coat A.And then, more preferably make the binding power of the adhesives of the bonding coat of formation single-sided adhesive tape 132 relative to the adhesives forming bonding coat B for more than equal.
By utilizing the single-sided adhesive tape 132 with high adhesion to be fixed the end of the laminating film after attaching, the winding can eliminated deflector roll from handrail stripping by the laminating film of fitting can be prevented.In addition, due to the binding power without the need to improving bonding coat A itself, so remain at the paste of surface of handrail when film can be suppressed to peel off.And then, by making the binding power of single-sided adhesive tape 132 be more than the binding power of bonding coat B, thus can prevent laminating film from floating from handrail.
The width of single-sided adhesive tape 132 is set to more than 2mm, is preferably positioned at (reference marks w on laminating film 1 with more than 1mm
1), more than 1mm is positioned at handrail R (reference marks w on the surface
2) mode attach.Thereby, it is possible to reliably prevent the laminating film 1 by fitting from peeling off from handrail R further.Make the length of single-sided adhesive tape 132 roughly the same with the width that laminating film 1 attaches to surface of handrail, or slightly long.
The method that laminating film 1 attaches to surface of handrail is not particularly limited, such as, the separate layer 2 being laminated in bonding coat A can be peeled off, while use rubber rollers, squeegee equipressure to merge be attached at surface of handrail.
The width that laminating film 1 attaches to surface of handrail and length suitably can adjust according to the size of handrail, such as, make that width is about 60 ~ 150mm, length is about 1 ~ 40m.Now, by being pre-formed mark 21 as being illustrated by Fig. 3, perforation, thus can the laminating film 1 of length will be needed simply to cut off to attach.
After attaching to surface of handrail, peel off the separate layer 2 being laminated in bonding coat B, start conveyer, start cleaning.Then, make the film fitting part of handrail after 2 ~ 5 weeks, stop conveyer in the mode that film fitting part does not stop in conveyer inside.After conveyer stops, peeling off laminating film 1 from surface of handrail, complete cleaning.Cleaning work, when carrying out 1 time and not eliminated by dust, carries out 2 ~ 3 times repeatedly.
Now, in laminating film 1, in bonding coat A, by to the region becoming film end under the state being bonded to surface of handrail, give the binding power larger than other region, thus can prevent laminating film in cleaning from floating from handrail, or peel off (with reference to Fig. 2,4,5).
In addition, do not improving the binding power (with reference to Fig. 2) of adhesives of the bonding coat A forming film end, or double-faced adhesive tape 131(is not set with reference to Fig. 4), single-sided adhesive tape 132(is with reference to Fig. 5) when, the floating of the laminating film in also preventing from cleaning by attaching method as shown in Figure 6, to peel off.
That is, as shown in Figure 6, attach by making the bonding coat B of film end be inverted to surface of handrail side, thus can improve by the binding power of laminating film 1 end of fitting.Now, preferably the width that turns back (with reference to symbol w in figure) of bonding coat B is set to more than 10mm.By turning back, width w is set to more than 10mm, thus can reliably prevent the laminating film 1 by fitting from peeling off from handrail R further.
