Abstract
Abstract This invention relates to a vacuum reel spool for use on a paper machine reel. The surface of the reel spool is perforated along substantially its entire length and the vacuum produced therein urges the ballooned portion of web formed between a previously wound roll and a new reel spool into the nip between the reel drum and reel spool at high speeds thereby permitting the reel to operate continuously at papermaking speeds.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
157 words
In a reel for continuously winding an on coming web into successive rolls, including: a driven reel drum adapted to support the web thereon; a reel spool; arm means supporting said reel spool and adapted to move said reel spool radially and circumferentially about the surface of said reel drum and be selectively engaged and disengaged in nipped relationship therewith to drive said reel spool disengaged; rail support means adapted to receive said spool from said arm means; wherein the improvement comprises the surface of said reel spool is perforated for substantially its entire face width; means producing sub-atmospheric pressure is operatively connected to said reel spool during at least a portion of its movement about the surface of said reel drum and thereby creating sub-atmospheric pressure within said reel spool whereby from the off going side between the rotating reel drum and the reel spool is urged onto the reel spool to commence being wound thereon.
Claim 2
Dependent Claim
157 words
In a reel for continuously winding an on coming web into successive rolls, including: a driven reel drum adapted to support the web thereon; a reel spool; arm means supporting said reel spool and adapted to move said reel spool radially and circumferentially about the surface of said reel drum and be selectively engaged and disengaged in nipped relationship therewith to drive said reel spool disengaged; rail support means adapted to receive said spool from said arm means; wherein the improvement comprises the surface of said reel spool is perforated for substantially its entire face width; means producing sub-atmospheric pressure is operatively connected to said reel spool during at least a portion of its movement about the surface of said reel drum and thereby creating sub-atmospheric pressure within said reel spool whereby from the off going side between the rotating reel drum and the reel spool is urged onto the reel spool to commence being wound thereon.
Claim 3
Dependent Claim
51 words
The apparatus as set forth in claim 1, wherein: said sub-atmospheric pressure producing means is connected to said reel spool by retractable semi-rigid coupling means engaging the end of said reel spool means and adapted to tolerate at least partial relative movement therebetween while maintaining subatmospheric pressure within said reel spool.
Claim 4
Dependent Claim
30 words
The apparatus as set forth in claim 1, wherein: said sub-atmospheric pressure producing means maintains a vacuum in said reel spool between about 0.1 and about 15 inches of mercury.
Claim 5
Dependent Claim
83 words
The apparatus as set forth in claim 1, wherein: said arm means supports said reel spool initially at a point about the upper periphery of said winder drum surface; said rail support means extend substantially horizontally from about the elevation of the axis of rotation of said reel drum; said sub-atmospheric pressure is applied to the reel spool when said spool is near the top of said reel drum and maintained substantially until the reel spool is deposited onto said rail support means.
Claim 6
Independent Claim
178 words
A method of continuously forming wound rolls of web material from a constantly oncoming supply comprising the steps: a. nipping the oncoming web between a driven reel drum and a first reel spool, thereby winding said web material onto said first reel spool; b. positioning a perforated second reel spool near the surface of said reel drum; c. nipping said second perforated reel spool with said reel drum and bringing said second reel spool into the space between the previously wound roll and said reel drum; disengaging the wound roll on said first reel spool from a nip relationship with said reel drum and removing it from the vicinity, thereby slowing its rotational speed relative thereto and permitting the web to balloon therebetween; e. producing sub-atmospheric pressure within said second reel spool, thereby urging the ballooned web into proximity to the reel spool surface and into the nip between said reel spool and reel drum, thereby breaking the web between said first and second reel spools and initiating the formation of another roll on said second reel spool.
Claim 7
Independent Claim
178 words
A method of continuously forming wound rolls of web material from a constantly oncoming supply comprising the steps: a. nipping the oncoming web between a driven reel drum and a first reel spool, thereby winding said web material onto said first reel spool; b. positioning a perforated second reel spool near the surface of said reel drum; c. nipping said second perforated reel spool with said reel drum and bringing said second reel spool into the space between the previously wound roll and said reel drum; disengaging the wound roll on said first reel spool from a nip relationship with said reel drum and removing it from the vicinity, thereby slowing its rotational speed relative thereto and permitting the web to balloon therebetween; e. producing sub-atmospheric pressure within said second reel spool, thereby urging the ballooned web into proximity to the reel spool surface and into the nip between said reel spool and reel drum, thereby breaking the web between said first and second reel spools and initiating the formation of another roll on said second reel spool.
Claim 8
Independent Claim
185 words
A method of continuously forming wound rolls of web material from a constantly oncoming supply comprising the steps: a. initially wrapping the oncoming web onto a first reel spool; b. driving said first reel spool to wind said web thereon; c. positioning a perforated second reel spool near the reel drum surface above the web being carried thereon; d. producing a sub-atmospheric pressure in said second reel spool; e. nipping saiD second reel spool with said reel drum thereby engaging the web; f. slowing the speed of said first reel spool thereby allowing a ballooned portion of web to emerge between said first and second reel spools; g. rotating said second reel spool downwardly about said reel drum into proximity with the ballooned portion of web whereby the layer of air carried with the web is substantially absorbed by the entry air into said reel spool via its perforations, thereby urging the ballooned web portion into the nip between said second reel spool and reel drum whereupon the web is torn and the winding of a new web is initiated on said second reel spool.
