Abstract
Abstract A packaging machine, of the type comprising a bed mounted on support legs, two uprights rigidly connected to the bed and upwardly projecting therefrom, and a working head carried by said uprights. The bed (1) comprises a rectangular box-formed sheet metal frame and two central, longitudinal, side-by-side cross-members (1e, 1f); the constituent elements of at least part of the machine working units being mounted directly on said cross-members, and a space for housing removable roller tables being provided between these cross-members (1e, 1f) and the longitudinal sidepieces (1a, 1b) of the bed.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
90 words
1) A packaging machine, of the type comprising a bed mounted on support legs, two uprights rigidly connected to the bed and projecting upwards therefrom, and a working head carried by said uprights, characterised in that the bed consists of a rectangular box-formed sheet metal frame and two central, longitudinal, side-by-side cross-members, the constituent elements of at least part of the machine working units being mounted directly on said cross-members, and a space for housing removable roller tables being provided between these cross-members and the longitudinal sidepieces of the bed.
Claim 2
Dependent Claim
90 words
1) A packaging machine, of the type comprising a bed mounted on support legs, two uprights rigidly connected to the bed and projecting upwards therefrom, and a working head carried by said uprights, characterised in that the bed consists of a rectangular box-formed sheet metal frame and two central, longitudinal, side-by-side cross-members, the constituent elements of at least part of the machine working units being mounted directly on said cross-members, and a space for housing removable roller tables being provided between these cross-members and the longitudinal sidepieces of the bed.
Claim 3
Dependent Claim
42 words
2) A packaging machine as in claim 1), wherein the rectangular box-for-med sheet metal frame comprises two endpieces substantially of C-shaped cross-section, and two sidepieces of closed tubular cross-section, these latter being obtained by welding together two sheets disposed side by side.
Claim 4
Dependent Claim
31 words
3) A packaging machine as in claim 1), wherein said longitudinal cross-members consist of sheet metal plates fixed at their ends to the minor sides or endpieces of the rectangular frame.
Claim 5
Dependent Claim
31 words
4) A packaging machine as in claim 3), wherein said longitudinal plate cross-members comprise at least one recess or aperture for housing a correspondingly. shaped part of an interchangeable working device.
Claim 6
Dependent Claim
40 words
5) A packaging machine as in claim 4), wherein said working device is a taping unit, the sidepieces of which are configured in such a manner as to exactly fit into said housing apertures or recesses in the plate cross-members.
Claim 7
Dependent Claim
54 words
6) A packaging unit as in claim 3), wherein said working device is a conveying unit comprising, at one end, a geared motor with a first pair of drive rollers, and at its other end, a pair of position-adjustable mobile carriages, each carrying an idle return roller, conveyor belts being mounted on said rollers.
Claim 8
Dependent Claim
74 words
7) A packaging machine as in claim 6), wherein each of said mobile carriages consists of a plate from which projects the support pin for a return roller, said pin passing through an aperture in the longitudianl cross-members, the position of said plate being determined by a longitudinal adjustment bolt, the head of which serves as an abutment against which the plate rests under the thrust determined by the tensioning of the conveyor belts.
Claim 9
Dependent Claim
44 words
8) A packaging machine as in claim 1), wherein each roller table consists of a pair of sidepieces joined together by respective spacer means and having idle rollers mounted thereon, each roller table resting, by the ends of its sidepieces, onto the bed endpieces.
Claim 10
Dependent Claim
30 words
9) A packaging machine as in claim 8), wherein the bed endpieces comprise,. in the lower part, inwardly projecting edges on which the ends of said roller table sidepieces rest.
Claim 11
Dependent Claim
24 words
10) A packaging machine as in claim 8), wherein the inner sidepieces of each roller table form a protection guard for the conveyor belts.
Claim 12
Dependent Claim
29 words
11) A packaging machine as in claim 1), wherein the lateral support uprights for the upper working head are joined together at their upper end by a stiffening cross-member.
Claim 13
Dependent Claim
44 words
12) A packaging machine as in claim 11), wherein each of the lateral uprights houses, in known manner, a slidable support carriage for the upper working head, a connection arm for the working head projecting towards the centre of the machine from each carriage.
Claim 14
Dependent Claim
23 words
13) A packaging machine as in claim 12), wherein the working head is interchangeable on said connection arms of the slidable support carriages.
Claim 15
Dependent Claim
41 words
14) A packaging machine as in claim 12), wherein said connection arms terminate with longitudinal bars, the working head being mounted on said bars by way of means for adjusting the inclination of the head in respect to the horizontal plane.
Claim 16
Dependent Claim
29 words
15) A packaging machine as in claim 11), wherein the. slidable support carriages are identical and are mounted on said uprights in specular symmetry, independently one from the other.
Claim 17
Dependent Claim
41 words
16) A packaging machine as in claim 11), wherein the slidable support carriages are moved in known manner by worm screws, mounted rotatably but not slidably in said uprights, means being also provided for synchronising the rotation of the two worms.
Claim 18
Dependent Claim
22 words
17) A packaging machine as in claim 16), wherein said synchronising means consist of a drive housed in said upper connection cross-member.
