Abstract
Abstract Apparatus for processing a sheet of material such as cardboard intended for making a folding box or case, comprises a stamping plate for carrying the sheet and co-operable with a tool. The stamping plate lies on a table plate of a frame structure which has holders for releasably carrying a form which extends parallel to the table plate, and at least one bridge assembly which extends movably above the table plate. A carriage is carried on the bridge assembly and moves transversely with respect to the direction of travel thereof. The carriage carries at least one vertically movable pressure member directed towards the table plate.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
155 words
Apparatus for processing a sheet of material, comprising: a table plate adapted to receive a stamping plate for receiving a said sheet of material thereon; a stamping tool operatively associated with the stamping plate; a form means; tool holding means for releasably carrying the form means substantially parallel to the table plate; guide track means extending over the table plate at a spacing therefrom and disposed movably thereabove; carriage means carried on the guide track means and movable in a direction transverse with respect to the direction of movement of the guide track means; at least one vertically movable pressure member carried on the carriage means and operatively directed towards said table plate; and at least one lateral defining member which is arranged on the table plate in such a way as to be movable and fixable in a steplessly variable manner thereon wherein said lateral defining member carries holding means for said form means.
Claim 2
Dependent Claim
155 words
Apparatus for processing a sheet of material, comprising: a table plate adapted to receive a stamping plate for receiving a said sheet of material thereon; a stamping tool operatively associated with the stamping plate; a form means; tool holding means for releasably carrying the form means substantially parallel to the table plate; guide track means extending over the table plate at a spacing therefrom and disposed movably thereabove; carriage means carried on the guide track means and movable in a direction transverse with respect to the direction of movement of the guide track means; at least one vertically movable pressure member carried on the carriage means and operatively directed towards said table plate; and at least one lateral defining member which is arranged on the table plate in such a way as to be movable and fixable in a steplessly variable manner thereon wherein said lateral defining member carries holding means for said form means.
Claim 3
Dependent Claim
25 words
Apparatus as set forth in claim 1 wherein said pressure member comprises a roller having a peripheral surface thereby adapted to produce strip-like pressure regions.
Claim 4
Dependent Claim
32 words
Apparatus as set forth in claim 2 wherein said roller is rotatable about an axis in a vertically movable support means, and including an actuating means for vertically moving said support means.
Claim 5
Dependent Claim
15 words
Apparatus as set forth in claim 3 wherein said actuating means is a piston-cylinder unit.
Claim 6
Dependent Claim
22 words
Apparatus as set forth in claim 1 and further including an actuator means for displacing said carriage along said guide track means.
Claim 7
Dependent Claim
38 words
Apparatus as set forth in claim 1 and including a support structure providing side portions, wherein said lateral defining member is displaceable parallel to a said side portion which projects upwardly beyond the level of said table plate.
Claim 8
Dependent Claim
36 words
Apparatus as set forth in claim 6 wherein said lateral defining member is operatively connected to at least one guide spindle means rotatably disposed in said side portion, for producing movement of said lateral defining member.
Claim 9
Dependent Claim
48 words
Apparatus as set forth in claim 5 wherein said actuator means comprises an endless elongate actuating means, and an actuating wheel adapted to displace said elongate actuating means in a closed-loop movement, a portion of said carriage being connected to said elongate actuating mean for moving said carriage.
Claim 10
Dependent Claim
55 words
Apparatus as set forth in claim 1 and including a support structure providing side portions, wherein said guide track means is provided on a bridge assembly which extends over said table plate at a spacing therefrom and which is mounted on said side portions of said support structure at both ends of said bridge assembly.
Claim 11
Dependent Claim
31 words
Apparatus as set forth in claim 9 wherein said side portions provide elongate guide tracks, and wherein said bridge assembly is mounted on said guide tracks by means of rolling members.
Claim 12
Dependent Claim
26 words
Apparatus as set forth in claim 10 wherein said guide tracks comprise grooves formed in respective ones of said side portions and facing towards each other.
Claim 13
Dependent Claim
23 words
Apparatus as set forth in claim 11 wherein said bridge assembly comprises side plate assemblies carrying rollers engaging into said mutually facing grooves.
Claim 14
Dependent Claim
29 words
Apparatus as set forth in claim 9 wherein said bridge assembly comprises a beam member having a lower portion providing said guide track means for movably supporting said carriage.
Claim 15
Dependent Claim
20 words
Apparatus as set forth in claim 13 wherein said carriage is mounted on said guide track means by roller means.
Claim 16
Dependent Claim
46 words
Apparatus as set forth in claim 9 wherein said bridge assembly further comprises control means at respective ends thereof, operable to engage with control means on said side portions for guiding said bridge assembly in a condition of parallelism with respect to itself during movement thereof.
Claim 17
Dependent Claim
23 words
Apparatus as set forth in claim 9 wherein operation of at least one of said bridge assembly and said pressure member is computer-controlled.
Claim 18
Dependent Claim
29 words
Apparatus as set forth in claim 1 wherein said pressure member comprises a ram portion operable by a piston cylinder means operable in a direction towards said table plate.
