  In FIG. 1, the predetermined portion F is a portion between the left side L and the linearly separable portion Q formed by perforations in a certain direction, and is continuous in a certain direction with a predetermined lateral width.

  The length of the laminated sheet continuous body T in a certain direction is a length that is a multiple of the predetermined sheet body length S1 that is the length of the laminated sheet body S in the certain direction, and is between the adjacent predetermined sheet bodies. This corresponds to a length obtained by adding a predetermined excision length E1, which is a fixed direction length of the excision E to be provided.

  (1-1) The base sheet portion P coincides with the laminated sheet continuous body T in a plan view, is continuous in a certain direction with a certain lateral width, and both sides are linear in a certain direction, Both sides are parallel.

  (1-2) The bonding sheet portion H (the other sheet portion) coincides with the predetermined portion F in plan view, is continuous in a certain direction with a certain lateral width, and both sides are in a certain direction. It is straight and both sides are parallel.

  (2) Laminate sheet manufacturing method

  (2-1) In order to provide the first region forming unit 10, the second region forming unit 20, and the main region 30 in the laminated sheet continuous body T, the first separating unit 15, the second separating unit 25, Three cut-off portions 35 are formed.

  The first region forming unit 10 is configured to release the portion along the left side L of the laminated sheet continuous body T of the bonding sheet portion H and the base sheet portion P laminated on the release sheet portion D together with the adhesive layer W. The first region 12 is formed from the release sheet portion D by being removed from the sheet portion D.

  The second region forming unit 20 forms the first region among the portions (corresponding to the predetermined portion F) along the cutout portion E of the bonding sheet portion H and the base sheet portion P stacked on the release sheet portion D. The part not included in the part 10 is removed from the release sheet part D together with the adhesive layer W to form the second region 22 composed of the release sheet part D.

  The second region forming unit 20 is in a direction perpendicular to the certain direction, most of the vicinity from the boundary with the first region 12 to the right side of the predetermined portion F (separable portion Q) (near the right side of the predetermined portion F). Part).

  The main region 30 does not include the first region 12, the second region 22, and the cut portion E, and is formed by stacking the release sheet portion D, the adhesive sheet portion H, and the base sheet portion P. In the fixed direction, the length of the main region 30 is slightly shorter than the predetermined sheet length S1.

  The base sheet portion P constituting the release sheet portion in the main region 30 is divided into a plurality of divided portions J by a separation line G · Ga orthogonal to the predetermined direction.

  The separation line Ga at the upper end in the fixed direction in each main region 30 extends over the base sheet portion P and the adhesive sheet portion H, and the part below the separation line Ga at the upper end in each main region 30 is a release sheet. This is for facilitating the work of peeling off the part D as a unit and attaching it to an object such as a delivery object by the adhesive layer W.

  In this way, each divided portion J is peeled off from the adhesive sheet portion H separately and used for different purposes (for example, peeled off from the address label and received from the delivery receipt slip or delivery destination). Etc.).

  (2-2) The first separating portion 15 is formed at the boundary between the first region forming portion 10 and the main region 30 in the bonding sheet portion H and the base sheet portion P.

  The second separating portion 25 is a left end portion (one side end portion) that is an end portion on the left side L side at the boundary between the second region forming portion 20 and the main region 30 in the adhesive sheet portion H and the base sheet portion P. ) Is formed so as to coincide with the end of the first separation portion 15.

  The right end portion (reverse side end portion) of the second separation portion 25 is from the left side in the direction orthogonal to the predetermined direction of the predetermined portion F in the base sheet portion P to the right side (separable portion Q, reverse side end). Of the entire width up to the predetermined portion F, the second separating portion 25 is formed in a portion of the base sheet portion P where the release sheet portion D (the bonding sheet portion H and the release sheet portion D) is not laminated. In order to avoid this reliably, it is assumed that it is located in the vicinity of the right side (separable portion Q) of the predetermined portion F (the vicinity that does not reach the right side).

  The third cut-off portion 35 is formed on the bonding sheet portion H and the base sheet portion P in the cut-out portion E. Of the second cut-off portions 25 facing the fixed direction across the cut-out portion E, It is formed so as to connect the right ends.

And the base sheet P extends as a whole from the left side L side toward the right side R side, and extends in a direction orthogonal to the fixed direction in a state of bifurcating symmetrically in the fixed direction. ing.

  In this way, the adhesive sheet part H and the base sheet part P peeled off from the release sheet part D are branched into two so as to be swept toward the left side L by the third separating part 35, The temporary attachment area between the adhesive sheet part H and the release sheet part D is reduced both in individual branches and in the total of two branches, and the temporary attachment force between them is reduced. The tension acting on the adhesive sheet portion H and the base sheet portion P at the time of peeling from the portion D is reduced in both the individual branches and the whole of the two branches.

  Therefore, the peeling from the release sheet portion D of the adhesive sheet portion H and the base sheet portion P between the second separation portion 25 and the third separation portion 35 and the left side L is substantially along the left side L. It can be performed as smoothly as possible based on the tension acting in the substantially constant direction.

  In addition, the second separation portion 25 is substantially perpendicular to the certain direction, and the third separation portion 35 is slightly inclined with respect to the second separation portion 25, thereby causing the width of each branch (the certain direction). ) Is gradually reduced from the left side L side toward the right side R side. Also in this respect, the peeling from the release sheet portion D of the adhesive sheet portion H and the base sheet portion P between the second separation portion 25 and the third separation portion 35 and the left side L is almost on the left side L. It contributes to being performed as smoothly as possible based on the tension acting in the substantially constant direction along.

(Border line) and the first side 50. The base sheet portion P on the right side of the separable portion Q of the laminated sheet body S can be separated into a plurality by the separable portion Qa, but the release sheet portion D is laminated on the back side. Not done.

  (3-4) Among the portions along the second side 60 near the specific position X, the small portion 30a on the side opposite to the first side 50 side (the side of the third side 70) from the specific position X is The main area 30 is configured. Deviating from the predetermined portion F, the base sheet portion P is not cut in the base sheet portion P in an attempt to form the second region 22 in the portion where the adhesive sheet portion H and the release sheet portion D are not stacked. This is for reliably avoiding the formation of.

  The first region forming part removes the base sheet part laminated on the release sheet part and the part along the one side of the other sheet part (0 layers or more) from the release sheet part together with the adhesive layer. Thus, the first region including the release sheet portion is formed.

  The second region forming part is the first region forming of the base sheet part laminated on the release sheet part and the part (part corresponding to the predetermined part) along the cut part of the other sheet part (more than zero layers). A portion not included in the portion is removed from the release sheet portion together with the adhesive layer to form a second region (not including the first region) including the release sheet portion.

  The second region forming portion is along a cut portion of the base sheet portion and other sheet portions (0 layers or more) stacked on the release sheet portion from the boundary with the first region in a direction transverse to the fixed direction. Most of the portion that reaches the end of the other side of the part, or from the boundary with the first region, for example, from one side to the other side (for example, 95% or more, preferably 97 to 99.5% or higher position).

  The main region does not include the first region, the second region, and the cut portion, and is formed by stacking a release sheet portion, a base sheet portion, and other sheet portions (zero or more layers). In a fixed direction, the length of the main region is generally slightly shorter than the predetermined sheet length.

  Examples of the main region include a release sheet part, an adhesive layer, another sheet part (an adhesive sheet part for peeling off the release sheet part and attaching the adhesive sheet to an object such as a delivery object), a temporary adhesive layer , One laminated in the order of the base sheet part (the one constituting the release sheet part), or the release sheet part, the adhesive layer, the base sheet part (the release sheet part is peeled off, and the adhesive layer is applied to an object such as a delivery item) Adhesive sheet part for stacking in order, or release sheet part, adhesive layer, base sheet part (for releasing the release sheet part and attaching it to an object such as a delivery item by the adhesive layer) An adhesive sheet portion), a temporary adhesive layer, and other sheet portions (those constituting the release sheet portion) may be laminated in this order.

  The sheet part (base sheet part or other sheet part) constituting the release sheet part in the main region may be divided into a plurality of parts by a separating line or the like. Each divided part can be separated from the adhesive sheet part and used for different purposes (for example, peeled off from the address label and used for a delivery receipt slip or a receipt from the delivery destination). Any one or more of the divided portions may be formed such that an adhesive layer is formed on the back side instead of the temporary adhesive layer and is fixed to the lower sheet portion.

  In addition, the sheet part (other sheet part or base sheet part) constituting the adhesive sheet part in the main region can also be divided into a plurality of parts by a cutting line or the like. In this case, 1 or 2 or more of each division | segmentation part of the sheet | seat part for adhesion | attachment can be peeled off from a release sheet part, respectively, and can be affixed on a target object. For example, such a division corresponds to the sheet part constituting the release sheet part, or the sheet part constituting the release sheet part in any divided part of the sheet part constituting the adhesive sheet part. As what corresponds to a plurality of divided portions, the adhesive sheet portion in a state where the release sheet portions are laminated can be peeled off from the release sheet portion and attached to an object.

  For example, a separable portion formed by a perforation or the like is provided between a predetermined portion including a portion along one side of the laminated sheet continuous body and the other side, or a boundary to be separated The line can also be specified by physical means other than the printable or separable part.

  As described above, when the other predetermined portion is included in addition to the one predetermined portion, the first region forming portion, the second region forming portion, and the main region can be provided for the other predetermined portion.

  (2-2) The first separation portion is formed at the boundary between the first region forming portion and the main region in the base sheet portion and the other sheet portions (zero layers or more).

  The second cut-off portion has one side end portion which is an end portion on one side side at the boundary between the second region forming portion and the main region in the base sheet portion and other sheet portions (0 layers or more). It forms so that it may correspond with the edge part of a 1st separation part.

  The reverse side end of the second separating portion is, for example, the one side of the full width from the one side to the reverse side in the direction orthogonal to the predetermined direction of the predetermined portion of the base sheet portion. Be sure to be located at the opposite end, or to deviate from the predetermined part and to form the second separation part in the part of the base sheet part where the release sheet part is not laminated. Therefore, the one side may be located in the vicinity of the opposite end (the vicinity not reaching the opposite end).

  The third cut-off portion is formed on the base sheet portion in the cut-out portion and other sheet portions (0 layers or more), and the second cut-out portion facing the fixed direction across the cut-out portion. It forms so that the opposite side edge part which is an edge part on the opposite side to one side may be tied. It is preferable that a 3rd separation part is provided in the part corresponding to a predetermined part among cutting parts.

  Reverse side end in the second cut-off portion (when one side of the full width from one side to the reverse side in the direction orthogonal to the predetermined direction of the predetermined portion is located in the vicinity of the reverse side And the vicinity of the reverse side end of the third cut-off portion connected to the reverse side end is a curved portion convex toward the side opposite to the one side. Can be formed. In this case, even if a slight deviation occurs in the positional relationship between the position of the edge in the fixed direction of the cut portion and the second cut-out portion and the third cut-off portion, the constant end portion of the opposite side of the second cut-out portion is constant. It can be prevented that the position in the direction orthogonal to the direction and the form of the vicinity of the opposite end of the second separation portion are greatly affected. More specific examples include an example in which the opposite end portion of the second separation portion is located near the apex of the curved portion, an example in which the apex is located between the apex and the base, and the like.

  Such a cut-off portion can be formed efficiently at a high speed using, for example, a rotary die cutter using an etching blade mold.

  (2-3) From a laminated sheet continuous body that is continuous in a certain direction and having a first region forming portion, a second region forming portion, and a main region, a first separating portion, a second separating portion, and a third The base sheet part between the cut-off part and one side and the other sheet part (0 layers or more) as a peeling and removing part as a whole, continuously in a substantially constant direction, together with the adhesive layer from the release sheet part By sequentially peeling and removing, the first region and the second region are formed.

  The 1st field which consists of a mold release sheet part can be formed as what was continued in the above-mentioned fixed direction along one side including a cut part.

  Moreover, the 2nd area | region which consists of a mold release sheet | seat part can be formed in the state which followed the area | region which consists of a mold release sheet | seat part which can be similarly formed in a cutting part in the said fixed direction.

  Subsequently, the laminated sheet body as a single unit can be manufactured one after another by cutting out the cut portion.

  In addition, after forming the first region composed of the release sheet portion, if necessary, the side of the one side in the first region (between the one side and the main region) is cut and laminated. The width of the first region of the sheet body (the width in the direction orthogonal to the certain direction) can be narrowed to a desired width. As a result, the width of the base sheet portion to be peeled and removed from the release sheet portion in the first region forming portion and the other sheet portions (0 or more layers) is made as wide as possible mainly to withstand the tension in a certain direction, and the peeling removal is performed. The width of the first region formed by the above can be set to a desired width. For the same purpose, a separation line in the fixed direction is provided at a position corresponding to the desired width in the release sheet portion, and the release sheet portion, the base sheet portion, and ( While the other sheet portions (zero layers or more) are stacked, the base sheet portion and other sheet portions (zero layers or more) are peeled and removed from the release sheet portion between the separation line and the main region (ie, The release sheet portion exists only between the parting line and the one side, and the base sheet portion and the other sheet portion (zero layers or more) exist between the main region and the one side. It can also be peeled off in the state).

  In this laminated sheet body, the first region and the second region constituting the side edge of the main region formed by laminating the release sheet portion, the base sheet portion, and other sheet portions (zero layers or more) through the adhesive layer. An area | region consists of a release sheet part and does not have an adhesive layer. For this reason, the adhesive (concept including a pressure-sensitive adhesive) in the adhesive layer in the main region sticks out to the other laminated sheet body or other objects as it is or as it sticks out to the side over time. Is prevented from occurring.

  In this laminated sheet body, the outer periphery of the main region does not face the outer periphery of the laminated sheet body, and a part of the outer periphery of the main region (as short as possible, for example, a portion along the direction of the outer periphery) Only the portion of 5% or less of the length, preferably the portion of 0.5 to 3% or less) faces the outer peripheral edge of the laminated sheet body, which can substantially prevent inconvenience due to protrusion of the adhesive. For example, in the outer peripheral edge in the lateral direction (for example, the orthogonal direction) to the certain direction of the laminated sheet body, most of one side side of the part from one side side to a certain position is the first region and the second region. It can be constituted by a region, and only a part on the opposite side can be constituted by a main region.

  (2-4) The base sheet portion between the first cut-off portion and one side and the other sheet portion (0 layers or more) extend in a substantially constant direction along one side, and the second cut The base sheet part between the separation part and the third separation part and one side and the other sheet part (0 layers or more) as a whole are directed from one side to the other side. , Extending in a direction transverse to a certain direction.

  The base sheet part between the first separation part, the second separation part and the third separation part and one side and the other sheet part (zero layers or more) as a whole in a substantially constant direction as described above. When the release sheet portion is continuously peeled and removed together with the adhesive layer, the base sheet portion to be peeled from the release sheet portion and the other sheet portions (zero layers or more) include the first separation portion and Also in the base sheet part between one side and the other sheet part (0 layers or more), the base sheet part between the second side and the third part and one side and (0 layer) Even in the other sheet portions (above), the tension acts substantially in the predetermined direction along one side.

  Therefore, as a whole, the base between the second and third separation parts and the one side extending in a direction transverse to a certain direction from the one side to the other side. The separation of the sheet portion and the other sheet portions (0 layers or more) is also performed based on the tension acting substantially in the constant direction along one side.

  (2-5) The third cut-off portion is directed toward the one side between the second cut-off portions connecting the opposite ends of the second cut-off portions facing each other in the predetermined direction. It may have one or more intruded shapes.

  In this case, the base sheet portion between the second and third cut portions and one side and the other sheet portion (zero layers or more), that is, the base sheet portion to be peeled off from the release sheet portion And the other sheet portion (0 layer or more) extends in a lateral direction with respect to a certain direction in a state where it is branched into a plurality from the side of one side toward the side of the other side as a whole. .

  In this way, the base sheet portion peeled off from the release sheet portion and the other sheet portions (0 layers or more) are branched into a plurality so as to be scooped toward one side by the third separation portion. Accordingly, the temporary attachment area between the base sheet part and any other sheet part (zero layer or more) and the release sheet part is reduced both in the individual branches and in all the branches, Since the temporary adhesion force decreases, the tension acting on the base sheet part and other sheet parts (zero layers or more) when peeling from the release sheet part is the total of all branches even in individual branches Also decreases.

  Therefore, the separation of the base sheet portion between the second and third separation portions and one side and the other sheet portion (0 layer or more) is substantially constant along one side. It can be performed as smoothly as possible based on the tension acting in the direction.

  As a shape in which the third cut-off portion enters the one side between the second cut-off portions connecting the opposite ends of the second cut-off portions facing each other in the certain direction. For example, it can be substantially U-shaped or substantially V-shaped.

  Separation of the base sheet part between the second and third separating parts and one side and the other sheet part (zero layers or more) is substantially along the one side in substantially the constant direction. In order to perform as smoothly as possible based on the acting tension, the width of the branch (the width in the constant direction) is gradually reduced from the side of one side toward the side of the other side. It is preferable to do. For example, the second cut-off portion is substantially perpendicular to the predetermined direction, and the third cut-off portion is inclined with respect to the second cut-off portion so that the second cut-off portion moves from one side to the other side. It can be reduced gradually.

  (2-6) The length (corresponding to the length of the branch perpendicular to the certain direction) that the third cut-off portion enters between the second cut-off portions toward the one side. , Or more than a quarter of the length of the second cut portion in the direction perpendicular to the certain direction (or more than one third, more than one half, more than two thirds, more than three quarters, Or 4/5 or more).

  A portion where the third separation portion enters between the two second separation portions toward the one side may reach the first region.

  The widths in the certain direction of the branches other than the end and the base can be equal to each other, but are not necessarily limited thereto.

  The width in the certain direction of the portion other than the end portion and the base portion in each branch may be, for example, 1/20 to 1/2 of the certain direction width of the cut portion.
