Shiftable packet mould partitions

Claim 2

In a packet mold including a number of generally parallel mold partition plates or support walls which are movable in regard to each other, a rail-type supporting and transporting system, comprising: a. first and second rails, said rails each including first and second parallel spaced-apart tracks extending generally transversely to the plane of the partition plates; and b. two wheeled structures attached to each said partition plate, each of said rails having respectively one of the wheeled structures associated therewith, each said wheeled structure being movable along respectively one track of one said rail, the corresponding wheeled structure of each adjacent partition plate being movable along the second track of said last mentioned rail, so as to enable the wheeled structures to overlap each other in the direction of transport of said partition plates or support walls.

Claim 3

In a packet mold including a number of generalLy parallel mold partition plates or support walls which are movable in regard to each other, a rail-type supporting and transporting system, comprising: a. first and second rails, said rails each including first and second parallel spaced-apart tracks extending generally transversely to the plane or the partition plates; and b. two wheeled structures attached to each said partition plate, each of said rails having respectively one of the wheeled structures associated therewith, each said wheeled structure comprising first and second parts, said first part being movable along one track of one rail and extending in one direction lengthwise of the rail, said second part being movable along the second track of the same rail and extending in an opposite direction lengthwise of the rail, so as to enable the wheeled structures of adjacent plates or walls to overlap each other.

Claim 4

In a packet mold including a number of generalLy parallel mold partition plates or support walls which are movable in regard to each other, a rail-type supporting and transporting system, comprising: a. first and second rails, said rails each including first and second parallel spaced-apart tracks extending generally transversely to the plane or the partition plates; and b. two wheeled structures attached to each said partition plate, each of said rails having respectively one of the wheeled structures associated therewith, each said wheeled structure comprising first and second parts, said first part being movable along one track of one rail and extending in one direction lengthwise of the rail, said second part being movable along the second track of the same rail and extending in an opposite direction lengthwise of the rail, so as to enable the wheeled structures of adjacent plates or walls to overlap each other.

Claim 5

A system as claimed in claim 2, each said wheeled structure comprising a pair of wheels movable on opposite sides of the associated rail, shaft means rotatably journalling said wheels on said structure in predetermined spaced relationship along the lengthwise direction of partition plate transport.

Claim 6

A system as claimed in claim 3, each said rail being constituted of an I-beam.

Claim 7

A system as claimed in claim 4, said wheels being movable along the lower flanges of said I-beam.

Claim 8

A system as claimed in claim 4, said wheels bieng movable along the upper flanges of said I-beam.

Claim 9

A system as claimed in claim 3, each said rail comprising a box-like structure having an opening along the upper surface thereof, said wheels being movable within said box-like structure.

Claim 10

A system as claimed in claim 7, said box-like structure comprising a pair of parallel extending spaced U-beams, having the flanges thereof facing each other.

Claim 11

A system as claimed in claim 7, comprising guide rollers for said wheeled structure movable within said box-like structure.

Claim 12

A system as claimed in claim 7, comprising guide rollers for said wheeled structure movable exteriorly of said box-like structure.

Claim 13

A system as claimed in claim 2, comprising drive means for each said wheeled structure, said drive means including a toothed rail mounted on the upper surface of each said rail, a rotatable shaft connected to said partition plate, gear tooth means rigidly fastened to said shaft and adapted to cooperatively engage said toothed rail.

Claim 14

A system as claimed in claim 11, said drive means comprising a chain and sprocket drive assembly.
