Abstract
Abstract In apparatus for winding a web (e.g. of metal foil or the like) on a rotating reel, an ironer assembly for smoothing the web as it is added to the reel, including an ironer roll which rides on the reel, a pivotally suspended frame larger in mass than the ironer roll, and springs under compression between the frame and roll for resiliently supporting the frame on the roll, so that the weight of the frame augments the pressure exerted by the roll on the web.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
213 words
Web-winding equipment, including a. rotatable means for accepting wound layers of a continuous web; b. means for rotating said rotatable means so as to wind said web thereon to constitute a reel of layers; and c. an ironer roll rotatably adapted to ride by the force of gravity against, and to exert pressure on, the outermost layer of the web on said reel; wherein the improvement comprises: d. a body having a mass substantially greater than the mass of said ironer roll; e. means for movably connecting said ironer roll to said body, including resilient means acting between said body and said ironer roll, disposed and arranged so that relative movement of said body and said ironer roll effects resilient deformation of said resilient means, for supporting said body on said ironer roll and transmitting to said body motion of said ironer roll occurring in a direction that is radial with respect to said reel; and f. means for restraining said body for movement along a path so disposed that said ironer roll rides against said outermost layer of the web as aforesaid and the weight of said body acts on said ironer roll through said resilient means to augment the pressure exerted by said ironer roll-on said outermost layer of the web.
Claim 2
Dependent Claim
213 words
Web-winding equipment, including a. rotatable means for accepting wound layers of a continuous web; b. means for rotating said rotatable means so as to wind said web thereon to constitute a reel of layers; and c. an ironer roll rotatably adapted to ride by the force of gravity against, and to exert pressure on, the outermost layer of the web on said reel; wherein the improvement comprises: d. a body having a mass substantially greater than the mass of said ironer roll; e. means for movably connecting said ironer roll to said body, including resilient means acting between said body and said ironer roll, disposed and arranged so that relative movement of said body and said ironer roll effects resilient deformation of said resilient means, for supporting said body on said ironer roll and transmitting to said body motion of said ironer roll occurring in a direction that is radial with respect to said reel; and f. means for restraining said body for movement along a path so disposed that said ironer roll rides against said outermost layer of the web as aforesaid and the weight of said body acts on said ironer roll through said resilient means to augment the pressure exerted by said ironer roll-on said outermost layer of the web.
Claim 3
Dependent Claim
18 words
Equipment as defined in claim 1, wherein said resilient means urges said ironer roll away from said body.
Claim 4
Dependent Claim
24 words
Equipment as defined in claim 2, wherein said resilient means comprises at least one spring under compression between said ironer roll and said body.
Claim 5
Dependent Claim
27 words
Equipment as defined in claim 3, wherein said resilient means further includes auxiliary means for damping relative motion of said ironer roll and body toward each other.
Claim 6
Dependent Claim
43 words
Equipment as defined in claim 4, wherein said damping means comprises a hydraulic cylinder carried by one of said body and said ironer roll, and a piston movable within said cylinder and carried by the other of said body and said ironer roll.
Claim 7
Dependent Claim
57 words
Equipment as defined in claim 5, further including means for supplying coolant liquid to said web in a manner providing a spray of said liquid in the vicinity of said reel, and wherein said hydraulic cylinder is carried by said ironer roll and opens upwardly to receive said spray, said spray constituting hydraulic fluid for said cylinder.
Claim 8
Dependent Claim
31 words
Equipment as defined in claim 3, further including means for limiting the extent of relative separation of said ironer roll and said body in the direction of compression of said spring.
Claim 9
Dependent Claim
49 words
Equipment as defined in claim 1, wherein said means for restraining said body includes means for exerting an upward force on said body to reduce the effective pressure exerted by the weight of said body through said ironer roll on said outermost layer of the web on said reel.
Claim 10
Dependent Claim
24 words
Equipment as defined in claim 1, wherein the mass of said body is at least about two times the mass of said ironer roll.
Claim 11
Dependent Claim
142 words
Equipment as defined in claim 1, wherein said body comprises a first pair of rocker arms and a member extending between and connected to said rocker arms; wherein said means for restraining said body comprises a fixed frame and means pivotally connecting said first pair of rocker arms to said fixed frame for pivotal movement of said rocker arms about a horizontal axis; and wherein said means for connecting said ironer roll to said body includes a second pair of rocker arms respectively pivotally connected to said first pair of rocker arms for pivotal movement about a horizontal axis, and further includes resilient means comprising a pair of springs under compression between the rocker arms of said second pair and the rocker arms of said first pair, said ironer roll extending between and being journaled in said second pair of rocker arms.
