Abstract
Abstract The machine comprises a table 13 for supporting objects 3 comprised between a cardboard 4 and a plastic film 2. Blades 18 are provided on said table to perform longitudinal cuttings between the objects 3 and at the end of the table is placed a carriage 33 mobile on guides 30, said carriage comprising a tightening clamp 60 to drive the assembly made of the cardboard 4; the objects 3 and the film 2 according to direction of arrow f1. During the step by step return of the carriage 33, a blade supported by a second transverse carriage 70 performs the transverse cutting between the objects.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
172 words
Packaging and cutting apparatus comprising a packaging unit for packaging a plurality of objects between a supporting sheet and a covering film bonded to said sheet, a table located near said packaging unit to support said sheet and film to be cut between said objects, a set of blades fixedly placed in an arrangement transverse to said table, a first carriage placed at end of said table on longitudinal guides, said first carriage supporting at least one small bar vertically mobile to press said sheet and film on top thereof, whereby advance of said first carriage causes advance of said sheet and film which are longitudinally cut by said blades, the first carriage further supporting a second carriage placed on guides extending angularly to the guides on which the first carriage is moved, and said second carriage supporting at least one blade protruding above said first carriage, whereby said blade ensures cutting of said sheet and film in transversal direction thereof during a step by step action cycle of said first carriage.
Claim 2
Dependent Claim
172 words
Packaging and cutting apparatus comprising a packaging unit for packaging a plurality of objects between a supporting sheet and a covering film bonded to said sheet, a table located near said packaging unit to support said sheet and film to be cut between said objects, a set of blades fixedly placed in an arrangement transverse to said table, a first carriage placed at end of said table on longitudinal guides, said first carriage supporting at least one small bar vertically mobile to press said sheet and film on top thereof, whereby advance of said first carriage causes advance of said sheet and film which are longitudinally cut by said blades, the first carriage further supporting a second carriage placed on guides extending angularly to the guides on which the first carriage is moved, and said second carriage supporting at least one blade protruding above said first carriage, whereby said blade ensures cutting of said sheet and film in transversal direction thereof during a step by step action cycle of said first carriage.
Claim 3
Dependent Claim
47 words
Apparatus as set forth in claim 1, wherein said first carriage further supports a set of dies placed beneath the sheet and film covering it, and a set of vertically mobile punches to cooperate with said dies whereby causing formation of cuts in said sheet and film.
Claim 4
Dependent Claim
39 words
Apparatus as set forth in claim 1, wherein the small bar pressing the sheet and film transversely on the first carriage has a longitudinal groove lined up with the cutting edge of the blade driven by the second carriage.
Claim 5
Dependent Claim
65 words
Apparatus as set forth in claim 1 comprising a crimping jack supported by a fixed frame and having a mobile rod carrying a crimping bar bearing on rear portion of the sheet, film and objects advanced by the carriage at end of its advance stroke, whereby said advanced sheet is prevented to return back during the step by step return cycle of the first carriage.
Claim 6
Dependent Claim
110 words
Apparatus as set forth in claim 1, wherein the set of blades fixedly placed with respect to the table and transversely thereto comprises a set of cutting disks placed in parallel to each other on a common pin supported by a device with a lever connected to a component for pressing said disks on the periphery of a bearing cylinder placed beneath said table and protruding, up to upper level thereof, through an aperture provided in the table, said bearing cylinder being connected to a driving motor, whereby it cooperates to the driving of the sheet and film for performance of longitudinal cutting thereof during driving by the first carriage.
Claim 7
Dependent Claim
49 words
Apparatus as set forth in claim 1, comprising a common cross-beam supported by the first carriage, said cross-beam supporting control jacks for controlling motion of the small bar applying the sheet, film and objects on said first carriage and supporting punches cooperating with dies also supported by said carriage.
Claim 8
Dependent Claim
44 words
Apparatus as set forth in claim 6, wherein the punches are removably placed on a common bar fixed to guides sliding along columns constituting mounting elements for the cross-beam, whereby said punches can be changed over and are adjustable both in position and angularly.
Claim 9
Dependent Claim
44 words
Apparatus as set forth in claim 2, wherein the dies cooperating with the punches are formed into cores having a polygonal section and placed in grooves delimited by an entablature of the first carriage, whereby said dies are adjustable both in position and angularly.
Claim 10
Dependent Claim
45 words
Apparatus as set forth in claim 1, comprising a swivelling table placed at end of an entablature of the first carriage, said table being coupled to a jack controlling swivelling thereof for ejecting cut portions of sheet and film after perforMance of each transverse cutting.
Claim 11
Dependent Claim
73 words
Apparatus as set forth in claim 5, wherein the first carriage is driven along longitudinal guides by endles chains trained around sprocket wheels, one of said wheels being driven by a motor-reducer brake, said motor-reducer brake simultaneously driving the bearing cylinder of the blades performing the longitudinal cuttings through a free wheel, whereby said cylinder is no longer driven when said motor-reducer brake causes the step by step return of said first carriage.
Claim 12
Dependent Claim
64 words
Apparatus as set forth in claim 1, wherein the second carriage supporting the blades performing the transverse cuttings is moved along its guides by a cable rolled up on pulleys and connected to a double-effect jack, whereby said blades perform a first transverse cutting during a going on stroke of the jack and a second transverse cutting during a return stroke of said jack.
Claim 13
Dependent Claim
48 words
Apparatus as set forth in claim 1, comprising a band rolled on a guiding cylinder supported by the table and placed at the end of the first carriage, whereby said band is unrolled as said first carriage advances to support the sheet and film driven by said carriage.
Claim 14
Dependent Claim
72 words
Apparatus as set forth in claim 2, wherein a set of adjustable cams is placed fixedly beneath the first carriage, and a set of switches is supported by said carriage to control the step by step return of said first carriage and the successive operating cycles of the blade supported by said second carriage as well as the cuttings performed by the punches cooperating with the dies supported by the first carriage.
Claim 15
Dependent Claim
47 words
Apparatus as set forth in claim 1, wherein two cutting disks are placed near the edges of the sheet and film to cut two lateral falls thereof and wherein the bearing cylinder of said cutting disks form a driving and ejecting element for the falls thus formed.
Claim 16
Dependent Claim
67 words
Apparatus as set forth in claim 1 comprising a plastic film unrolled from a roll, cardboard sheets and film coming from a packaging unit and moved by the first carriage, whereby extraction from the packaging unit corresponds to end of an operating cycle of said packaging unit, and the performance of the transverse cuttings is then made during a next cycle of operation of said packaging unit.
Claim 17
Dependent Claim
132 words
Apparatus as set forth in claim 15, comprising a crimping jack supported by a fixed frame and having a mobile rod carrying a crimping bar, said crimping bar bearing on rear portion of the cardboard sheets advanced by the carriage at the end of its advance stroke and further comprising a cell detecting the end of successive cardboard sheets, said cell controlling stoppage of the advance of the first carriage as well as the control of the crimping jack of which the bearing bar is inserted into an interval separating two successive cardboard sheets while forming a no-return stop for the cardboard sheet which has been the more advanced by said first carriage and on which the transverse cuttings are performed during the step to step return course of said first carriage.
