Abstract
Abstract A machine for separating individual rolls from a combined roll of web material after it has been operated upon by a two drum slitter rewinding machine to form individual slits but unseparated rolls comprises a machine having a plurality of individual and distinct segments or parts. The first segment includes a tilting leaf type table on which the set of split rolls are placed while the winder shaft is removed. The table is operated to tilt it to move the combined split rolls without the winder shaft to deposit the roll into a second segment portion of the machine. The second segment includes means for applying pressure at the respective ends of the combined slit rolls in order to compress the combined rolls against the stop plate so that any misalignment or telescoping of the wound web material is eliminated. The straightened set of rolls is then rolled onto a third segment which conveys the entire set endwise towards a clamp and hammering mechanism. The fourth segment comprises a hammering mechanism that engages the combined roll while individual rolls are hammered until they are separated from the set. The remaining set of rolls is advanced then to a new position in which the remaining set of rolls is engaged while the outermost roll is hammered and separated from the remainder. The process is repeated until all the rolls in the set have been separated and are conveyed away from the machine. The machine is designed so that each additional set of rolls can be started through the first two segments while previous rolls are being separated by the third and fourth segments so that it is a continuous type machine.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
200 words
A device for separating individual short width rolls from a pre-slit composite roll of a plurality of interconneCted short width rolls, comprising a support housing, first, second and third support plates each having a composite roll receiving area and all being substantially coextensive in length and arranged side by side on said housing, first tilting means for tilting said first support plate to incline it toward said second support plate to deliver the composite roll thereon to said second support plate, first clamping means adjacent said second support plate engageable with the ends of the composite roll thereon and being movable axially from at least one of the respective ends inwardly to engage and axially compress the composite roll, second tilting means for tilting said second plate to incline it toward said third plate to deliver the compressed composite roll thereon to said third plate, second clamping means adjacent said third plate being engageable laterally against said composite roll inwardly of the outermost individual roll to hold the composite roll in position, and hammer means located alongside the outermost individual roll adjacent said third plate and being movable to hammer the individual roll to sever it from the composite roll.
Claim 2
Independent Claim
200 words
A device for separating individual short width rolls from a pre-slit composite roll of a plurality of interconneCted short width rolls, comprising a support housing, first, second and third support plates each having a composite roll receiving area and all being substantially coextensive in length and arranged side by side on said housing, first tilting means for tilting said first support plate to incline it toward said second support plate to deliver the composite roll thereon to said second support plate, first clamping means adjacent said second support plate engageable with the ends of the composite roll thereon and being movable axially from at least one of the respective ends inwardly to engage and axially compress the composite roll, second tilting means for tilting said second plate to incline it toward said third plate to deliver the compressed composite roll thereon to said third plate, second clamping means adjacent said third plate being engageable laterally against said composite roll inwardly of the outermost individual roll to hold the composite roll in position, and hammer means located alongside the outermost individual roll adjacent said third plate and being movable to hammer the individual roll to sever it from the composite roll.
Claim 3
Independent Claim
116 words
A device for separating individual short width rolls from a pre-slit composite roll of a plurality of interconnected short width rolls, comprising means for supporting said rolls, first operable pressure applying means engageable with the respective ends of said roll including a movable member movable to compact said composite roll and to subsequently release it, second operable clamping means overlying said supporting means including a movable clamp plate engageable with a side of said composite roll adjacent the end thereof inwardly from the endmost short width roll to hold it against movement, and third hammer means operable exterior of said clamping means for hammering the endmost short width roll to sever it from said composite roll.
Claim 4
Independent Claim
116 words
A device for separating individual short width rolls from a pre-slit composite roll of a plurality of interconnected short width rolls, comprising means for supporting said rolls, first operable pressure applying means engageable with the respective ends of said roll including a movable member movable to compact said composite roll and to subsequently release it, second operable clamping means overlying said supporting means including a movable clamp plate engageable with a side of said composite roll adjacent the end thereof inwardly from the endmost short width roll to hold it against movement, and third hammer means operable exterior of said clamping means for hammering the endmost short width roll to sever it from said composite roll.
Claim 5
Dependent Claim
55 words
A device according to claim 2, wherein said supporting means includes a tilt table aligned with said pressure applying means and a hammering station adjacent said tilt table, and means for raising one end of said tilt table to direct said roll after it is released by said pressure applying means into said hammering station.
Claim 6
Dependent Claim
63 words
A device according to claim 3 including an entrance table alongside said tilt table, said entrance table being pivoted on a side thereof adjacent said tilt table and means for raising said entrance table to shift the roll from a position thereon into said tilt table, said entrance table having guide means for the removal of a winding shaft from said composite roll.
Claim 7
Dependent Claim
