Abstract
Abstract A buckling-type paper sheet folder comprises at least two pairs of folding cylinders W1 and W2 and two folding pockets F1, F2. The adjustable sheet stops 65,66, embodied by stop rails, of the folding pockets F1, F2 are secured to endless belts 67,68,69 and 70 which are drivable, conjointly two and two, through a manually actuable shaft 79 or 80. Scales of length S1 to S8 are carried on scale bands 48 and 49 which are associated each with one of the folding pockets F1 or F2 and displaceable by, the respective drive shafts 79, 80 in synchronism with the sheet stops 65, 66. The scale bands 48 and 49 are mounted in the housing to be visible through windows which are provided with reference marks. The sheet stops 65 and 66 can be set to the desired position through the closed housing by means of knobs 81 and 82. To facilitate the setting of the sheet stops, a plurality of scales S1 to S8 is provided on each scale band, each associated with a folding manner and sheet size, and made separately noticeable by a light.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
138 words
A buckling-type folding machine comprising at least two folding cylinders arranged adjacent to each other, at least two folding pockets associated with said folding cylinders, each having a sheet stop rail, a sheet stop movable along said rail and defining a sheet deflector in front of an associated pocket, each stop being adjustable independently of each other to set the folded sizes and folding manner, a draw member secured to each stop, a drive shaft driving said draw member, means defining a fixed reference, a movable scale having at least one scale band associated with each pocket and connected to said drive shaft for movement thereon along with said draw member, said scale being settable in respect to said fixed reference to move said draw member to advance said stop in proportion to the setting of said scale.
Claim 2
Dependent Claim
138 words
A buckling-type folding machine comprising at least two folding cylinders arranged adjacent to each other, at least two folding pockets associated with said folding cylinders, each having a sheet stop rail, a sheet stop movable along said rail and defining a sheet deflector in front of an associated pocket, each stop being adjustable independently of each other to set the folded sizes and folding manner, a draw member secured to each stop, a drive shaft driving said draw member, means defining a fixed reference, a movable scale having at least one scale band associated with each pocket and connected to said drive shaft for movement thereon along with said draw member, said scale being settable in respect to said fixed reference to move said draw member to advance said stop in proportion to the setting of said scale.
Claim 3
Dependent Claim
71 words
A buckling-type folding machine according to claim 1, wherein said scale comprises a band having a plurality of parallel scales thereon of selected lengths having zero marks of each scale in alignment, said scales corresponding to respective folding procedures and being reduced relative to an indicated dimensional scale in a proportion corresponding to the proportion of the depth to which a sheet to be folded is introduced into the respective pockets.
Claim 4
Dependent Claim
55 words
A buckling-type folding machine according to claim 2, including a separate light source associated with each of said scales arranged adjacent said fixed reference, said housing having a window adjacent said fixed reference which are illuminated by said light sources and switch means associated with said light sources for illuminating lights for respective folding procedures.
Claim 5
Dependent Claim
48 words
A buckling-type folding machine according to claim 1, including a housing enclosing said pockets and said folding cylinders including a console portion having a cover with an opening through which respective scale bands are visible, and roller means mounting said scale bands below the opening of said cover.
Claim 6
Dependent Claim
62 words
A buckling-type folding machine according to claim 1, wherein said scale includes a plurality of spaced rollers, an endless band engaged with said rollers, a housing enclosing said pockets having a window therethrough through which said band being made of a transparent material and including a light for each band making selective bands visible through the window when the lights are lit.
Claim 7
Dependent Claim
36 words
A buckling-type folding machine according to claim 5 including electric drive connected to said drive shaft and a selector switch for each scale selected effective to illuminate the selected band and to move said drive shaft.
Claim 8
Dependent Claim
138 words
A buckling-type folding machine for folding sheets, comprising a machine housing, inlet feed means on said housing for the infeed of a sheet to be folded, folding means in said housing engageable with the sheet and effective to fold a plurality of times, pocket means in said housing associated with said folding means for receiving selective lengths of the sheet as it is guided through said folding means so as to position it for folding, an adjustable stop movable in said housing along said pocket means determining the position of said sheet, stop drive means in said housing for said stop, a scale indicator on said housing, a settable scale movable along said indicator and connected to said stop drive means and positioning said stop proportionally to the movement of said scale with reference to said scale indicator.
Claim 9
Dependent Claim
138 words
A buckling-type folding machine for folding sheets, comprising a machine housing, inlet feed means on said housing for the infeed of a sheet to be folded, folding means in said housing engageable with the sheet and effective to fold a plurality of times, pocket means in said housing associated with said folding means for receiving selective lengths of the sheet as it is guided through said folding means so as to position it for folding, an adjustable stop movable in said housing along said pocket means determining the position of said sheet, stop drive means in said housing for said stop, a scale indicator on said housing, a settable scale movable along said indicator and connected to said stop drive means and positioning said stop proportionally to the movement of said scale with reference to said scale indicator.
Claim 10
Dependent Claim
16 words
A buckling-type folding machine according to claim 7 wherein said drive means includes a manual drive.
Claim 11
Dependent Claim
55 words
A buckling-type folding machine according to claim 7, wherein said drive means includes an endless band carrying said stop and means for driving said endless band, said settable scale comprising a scale band having a plurality of individual scale indications thereon, roller means around which said scale band is guided connected to said drive means.
