Web cutting and rewind machine

Claim 2

A machine for rewinding a plurality of strips longitudinally cut from a continuous web, comprising: roll means; at least two rewind elements on which said strips can be respectively wound into rolls of predetermined axial dimensions; a pair of feed drums, each of a predetermined axial dimension, in peripheral engagement with said rolls; said roll means, rewind elements and feed drums being positioned for permitting a pair of said strips to pass through said roll means, over a respective feed roll and onto a respective element to form rolls; mounting means adjacent opposite ends of each of said elements along a direction parallel to the axes of said feed drums; and means for mounting said drums being respectively connected to said element mounting means; whereby strips can be wound into rolls of axial dimensions less than said predetermined dimensions upon a shifting together of said mounting means to lie adjacent the opposite ends thereof.

Claim 3

The machine according to claim 1, wherein said drum mounting means include rollers surrounding said drums and bearing against the periphery thereof, and means for preventing axial shifting of said drums relative to said rollers.

Claim 4

The machine according to claim 2, wherein said axial shifting preventing means comprise a peripheral groove on one end of each said drums and rims on said bearings in engagement with said grooves.

Claim 5

The machine according to claim 2, wherein said drum mounting means further include arm members interconnected together and to said element mounting means, said bearings being rotatably mounted on said arm members.

Claim 6

The machine according to claim 2, wherein said arm members are pivotally interconnected together and to said element mounting means, and said drum mounting means still further include means for adjusting the relationship between said arm members as well as between said element mounting means and said arm members, whereby said arm members may be moved outwardly of one another to facilitate replacement of the drums of axial dimensions greater than said predetermined drum axial dimensions upon shifting said mounting means relatively outwardly.

Claim 7

The machine according to claim 1, wherein each said drum is covered by abutting cover sections having a combined width corresponding to the width of the strip to be wound.

Claim 8

The machine according to claim 1, wherein said element mounting means include arm members pivotally connected to a base member, and a slide member being provided in sliding engagement with said base member, said slide member extending parallel to said axes.

Claim 9

A machine for rewinding a plurality of strips longitudinally cut from a continuous web, comprising: roll means; at least two rewind elements on which said strips can be respectively wound into rolls of predetermined axial dimensions; a pair of feed drums, each of a predetermined dimension, in peripheral engagement with said rolls; said roll means and said elements being mounted for rotation with said drums being resepctively positioned between said roll means and said elements; mounting means at opposite ends of each of said elements being independently shiftable relative to said elements along a direction parallel to the axes of said drums; and mounting means at opposite ends of each of said drums being independently shiftable relative to said drums and relative to said element mounting means; whereby drums of axial dimensions different from said predetermined axial dimension may be mounted by said drum mounting means upon shifting thereof, and whereby rolls of axial dimensions different from said predetermined axial dimension may be mounted by said element mounting means upon shifting thereof.

Claim 10

A machine for rewinding a plurality of strips longitudinally cut from a continuous web, comprising: roll means; at least two rewind elements on which said strips can be respectively wound into rolls of predetermined axial dimensions; a pair of feed drums, each of a predetermined dimension, in peripheral engagement with said rolls; said roll means and said elements being mounted for rotation with said drums being resepctively positioned between said roll means and said elements; mounting means at opposite ends of each of said elements being independently shiftable relative to said elements along a direction parallel to the axes of said drums; and mounting means at opposite ends of each of said drums being independently shiftable relative to said drums and relative to said element mounting means; whereby drums of axial dimensions different from said predetermined axial dimension may be mounted by said drum mounting means upon shifting thereof, and whereby rolls of axial dimensions different from said predetermined axial dimension may be mounted by said element mounting means upon shifting thereof.

Claim 11

The machine according to claim 8, wherein a slide member extends parallel to said axes, three mutually spaced plate members at least one of which being in sliding engagement with said slide member, and a pair of elongated slide guides extending parallel to said slide member, said element mounting means being connected with pairs of said plate members including said slideable plate, and said drum mounting means being connected with said guides, whereby said element and said drum mounting means are shiftable along said member independently of one another.

Claim 12

The machine according to claim 9, wherein said slideable plate member is located between the remaining plate members, and said guides extend from said remaining plate members toward one other and through said slideable plate member.
