Claims
- 1. A method of making pieces containing a pop-up structure from a continuous web, which method comprises steps of:
- providing a continuous web of printed sheet material designed to produce a series of interconnected blanks each extending transversely of said continuous web, said blanks each including a pair of basepieces and a pair of pop-up panels which pop-up panels are connected to each other along a common line,
- applying adhesive to selective locations on said moving web;
- manipulating a portion of said web so that one pop-up panel at least partially overlies the other pop-up panel creating a double-thickness portion of said web,
- die-cutting said double-thickness portion of said web along a contoured line to create at least one similarly contoured edge along both said pop-up panels without at the same time cutting the web portion constituting said basepieces,
- displacing said die-cut pop-up panels having said similarly contoured edges to position them atop one of said basepieces,
- thereafter manipulating said web to superimpose said basepieces atop each other with said pop-up panels sandwiched therebetween, and
- cutting said web transversely of the series of manipulated blanks to create a plurality of structurally identical flat individual pieces each containing a pop-up structure that moves away from the respective planes of both basepieces when piece is opened by pivoting said basepieces along a straight hinge line of interconnection therebetween, said pop-up panels forming a construction wherein said similarly contoured edges of the pop-up structure present an attractive appearance.
- 2. A method according to claim 1 wherein said web is folded along said common line so that one pop-up panel overlies the other.
- 3. A method according to claim 2 wherein said die-cutting is carried out along said common line.
- 4. A method according to claim 2 wherein said die-cutting is carried out along an edge opposite from the edge defined by said common line.
- 5. A method according to claim 2 wherein said die-cutting is carried out along the edge defined by said common line and along the opposite edge.
- 6. A method according to claim 1 wherein said basepieces are adjacent each other in said blank and said web is folded to superimpose one basepiece atop the other.
- 7. A method according to claim 6 wherein said adhesive pattern creates a false backbone between said superimposed basepieces which provides said straight hinge line of interconnection.
- 8. A method according to claim 6 wherein said die-cut pop-up panels are displaced to position them adjacent the line along which said basepieces are folded and which constitutes said straight hinge line of interconnection.
- 9. A method of making pieces containing a pop-up structure from a continuous web, which method comprises steps of:
- providing a continuous web of printed sheet material designed to produce a series of interconnected blanks each extending transversely of said continuous web, said blanks each including a pair of basepieces and a pair of pop-up panels which panels are connected to each other along a common line,
- applying adhesive to selective locations on said moving web including one of said pop-up panels;
- folding a portion of said web so that one pop-up panel at least partially overlies the other pop-up panel creating a double-thickness portion of said web,
- severing said web into at least two parts, one of which contains said pair of pop-up panels,
- die-cutting said double-thickness portion of said web along a contoured line to create at least one similarly contoured edge along both said pop-up panels without at the same time cutting the web portion constituting said basepieces,
- displacing part of said web containing said die-cut pop-up panels having said similarly contoured edges to position them atop one of said basepieces,
- thereafter manipulating said web to superimpose said basepieces atop each other with said pop-up panels sandwiched therebetween, and
- cutting said web transversely of the series of manipulated blanks to create a plurality of structurally identical flat individual pieces each containing a pop-up structure that moves away from the respective planes of both basepieces when piece is opened by pivoting said basepieces along a straight hinge line of interconnection therebetween, said pop-up panels forming a construction wherein said similarly contoured edges of the pop-up structure present an attractive appearance.
