Abstract
A method and an apparatus for producing folders of the kind comprising two cover sheets, a spine, which is connected with the cover sheets by means of creasing lines, and a binding agent, which is applied to the inside of the spine and which is activable to connect sheets inserted between the cover sheets to the spine. The binding agent is applied to the spine and to the cover sheets while the cover sheets are essentially parallel to each other and perpendicular to the spine.
Claims16
A method for producing folders of the kind including two cover sheets, a spine with a first log connected in a perpendicular orientation to a central connector through a first fold line and a second leg connected in a perpendicular orientation to the central connector through a second fold line, creasing lines connecting the first and second legs of the spine with the cover sheets, and a binding agent which is applied to an inner side of the spine and which is activable to connect sheets inserted between the cover sheets to the spine, comprising the following steps:
- folding a folder blank such that at least two parts thereof which are to define the first and second legs of the spine in the folder will be essentially parallel to each other and to a first plane and perpendicular to a second plane formed by the central connector of the spine;
- and
- applying the binding agent to the spine on at least the central connector, the first and second fold lines, and the first and second legs while the first and second legs are kept essentially parallel to each other and to the first plane and perpendicular to the second plane formed by the central connector of the spine.

- means for folding a folder blank which is not provided with binding agent such that at least two parts thereof which are to define the first and second legs of the spine in the folder will be essentially parallel to each other and to a first plane and perpendicular to a second plane formed by the central connector of the spine;
- and
- means disposed above the inner side of the spine for applying hot-melt binding agent to the spine on at least the central connector, the first and second fold lines, and the first and second legs while the first and second legs are kept essentially parallel to each other and to the first plane and perpendicular to the second plane formed by the central connector of the spine.
