Abstract
Abstract A method and an apparatus for folding paperlike material, such as documents, which may have different quality and length and are conveyed in assembled form or successively in a transport track, said paperlike material having a leading and a trailing edge and being provided with a fold at a location between its leading and its trailing edge by bending the leading edge and the contiguous portion of the material out of the transport track during conveying of the material until the trailing edge reaches a predetermined position and creating a sharp folding edge by bringing the edge to be folded between folding means by a folding blade moving substantially in the transport track.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
222 words
An apparatus for folding paperlike material, such as documents, comprising: a transport track having transport means for transporting the paperlike material, and folding rollers arranged downstream of said transport means as viewed in the transport direction; a swiveling folding blade having a free end that swivels into a nip between two folding rollers, said free end swiveling substantially tangentially to said transport track; and guide means arranged between said transport means and said folding rollers, said guide means including deflection means for deflecting at least a leading edge of said paperlike material and including a guide member having a deflection face arranged between said transport means and said folding rollers, said deflection face arranged for swiveling between a first position intersecting said transport track and a second position that does not intersect said track, a guide plate that is substantially contiguous to said deflection face when said guide member is in said first position, said guide plate being positioned between said transport means and said folding rollers outside said transport track, and a second guide plate arrangement upstream and substantially parallel to said guide plate at a relatively small distance from said guide plate, said second guide plate being arranged in a swiveling relationship to said guide plate, and a distance between said guide plate and said second guide plate being variable.
Claim 2
Independent Claim
222 words
An apparatus for folding paperlike material, such as documents, comprising: a transport track having transport means for transporting the paperlike material, and folding rollers arranged downstream of said transport means as viewed in the transport direction; a swiveling folding blade having a free end that swivels into a nip between two folding rollers, said free end swiveling substantially tangentially to said transport track; and guide means arranged between said transport means and said folding rollers, said guide means including deflection means for deflecting at least a leading edge of said paperlike material and including a guide member having a deflection face arranged between said transport means and said folding rollers, said deflection face arranged for swiveling between a first position intersecting said transport track and a second position that does not intersect said track, a guide plate that is substantially contiguous to said deflection face when said guide member is in said first position, said guide plate being positioned between said transport means and said folding rollers outside said transport track, and a second guide plate arrangement upstream and substantially parallel to said guide plate at a relatively small distance from said guide plate, said second guide plate being arranged in a swiveling relationship to said guide plate, and a distance between said guide plate and said second guide plate being variable.
Claim 3
Dependent Claim
39 words
An apparatus as claimed in claim 1, wherein said free end of said folding blade is displaced at a speed equal to a transporting speed of said transport track at least when said folding blade approaches said folding rollers.
Claim 4
Dependent Claim
66 words
An apparatus as claimed in claim 2, wherein said transporting track is stopped when an edge of the paperlike material to be folded reaches a desired position, and a drive means for said folding blade is then coupled to a drive means for said transport track, and subsequently, said drive means for the folding blade and said drive means for said transport track are started jointly.
Claim 5
Dependent Claim
23 words
An apparatus as claimed in claim 3, wherein said transport track is stopped after a speed of said transport track has been reduced.
Claim 6
Dependent Claim
31 words
An apparatus as claimed in claim 2, wherein swiveling of said folding blade is related electronically by a start-up procedure to the position of a trailing edge of the paperlike material.
Claim 7
Dependent Claim
23 words
An apparatus as claimed in claim 1, wherein said folding blade and said second guide plate are mounted on a same swivel shaft.
Claim 8
Dependent Claim
24 words
An apparatus as claimed in claim 6, wherein said folding blade and said second guide plate are arranged to swivel independently from one another.
Claim 9
Dependent Claim
29 words
An apparatus as claimed in claim 1, wherein said second guide plate includes an end bent towards said folding rollers at said side where said guide member is located.
Claim 10
Independent Claim
236 words
An apparatus for folding paperlike material, such as documents, comprising: a transport track having transport means and folding rollers arranged in a downstream direction as viewed in the transport direction; a swiveling folding blade having a free end that swivels into a nip between two folding rollers, said free end swiveling substantially tangentially to said transport track; and guide means arranged between said transport means and said folding rollers, said guide mans comprising deflection means for deflecting at least the leading edge of the paperlike material, said deflection means including a guide member having a deflection face arranged between said transport means and said folding rollers, said deflection face arranged for swiveling between a first position intersecting said transport track and a second position that does not intersect said track, wherein a guide plate that is substantially contiguous to said deflection face when said guide member is in said first position is positioned between said transport means and said folding rollers outside said transport track, and wherein a second guide plate is arranged upstream and substantially parallel to said guide plate at a relatively small distance from said guide plate, and wherein said guide plate is arranged in a swiveling relationship to said guide plate such that said distance between said guide plate and said second guide plate is variable, and wherein said folding blade and second guide plate are mounted on a same swivel shaft.
Claim 11
Independent Claim
236 words
An apparatus for folding paperlike material, such as documents, comprising: a transport track having transport means and folding rollers arranged in a downstream direction as viewed in the transport direction; a swiveling folding blade having a free end that swivels into a nip between two folding rollers, said free end swiveling substantially tangentially to said transport track; and guide means arranged between said transport means and said folding rollers, said guide mans comprising deflection means for deflecting at least the leading edge of the paperlike material, said deflection means including a guide member having a deflection face arranged between said transport means and said folding rollers, said deflection face arranged for swiveling between a first position intersecting said transport track and a second position that does not intersect said track, wherein a guide plate that is substantially contiguous to said deflection face when said guide member is in said first position is positioned between said transport means and said folding rollers outside said transport track, and wherein a second guide plate is arranged upstream and substantially parallel to said guide plate at a relatively small distance from said guide plate, and wherein said guide plate is arranged in a swiveling relationship to said guide plate such that said distance between said guide plate and said second guide plate is variable, and wherein said folding blade and second guide plate are mounted on a same swivel shaft.
Claim 12
Dependent Claim
24 words
An apparatus as claimed in claim 9, wherein said folding blade and said second guide plate are arranged to swivel independently from one another.
