Web splicer

Claim 2

For use in a web splicer, a make-ready unit comprising a support, means mounting said support for pivotal movement, said support having a terminal edge portion remote from said mounting means, said terminal edge portion being in the form of a plurality of fingers spaced transversely of said support and forming a longitudinal extension of said support, at least certain of said fingers having terminal stop means remote from said support for longitudinally positioning a starter web on said support, and hold down means carried by said support for holding a new web on said support.

Claim 3

The device of claim 1 together with positioning means for moving said unit between a make-ready position and a running position.

Claim 4

The device of claim 1 wherein there is a web roll, said fingers overlap said web roll, said web roll being grooved in alignment with said fingers, and said fingers upon pivoting of said support being movable into said web roll in recessed relation for directing a starter web against said web roll to initiate feeding of a new web.

Claim 5

The device of claim 3 wherein said hold down means is a roll overlying said finger and cooperable with said web roll when said fingers move into said web roll.

Claim 6

The device of claim 1 wherein there are two web rolls mounted in cooperating web feeding relation and defining a nip therebetween, said fingers overlap one of said web rolls, said one web roll being adjacent said support and being grooved in alignment with said fingers, and said fingers upon pivoting of said support being movable into said one web roll in recessed relation for directing a starter web directly into said nip by said one roll and into adhered engagement with a running web passing through said nip.

Claim 7

The device of claim 5 together with positioning means for moving said unit between a make-ready position and a running position.

Claim 8

The device of claim 5 wherein there is a second of said make-ready unit positioned for cooperation with the other of said web rolls, and said other web roll having grooves therein for reception of fingers of said second make-ready unit.

Claim 9

The device of claim 7 wherein the grooves in said web rolls are in alignment.

Claim 10

The device of claim 5 wherein said running web enters said nip around the other of said rolls.

Claim 11

For use in a web splicer, a make-ready unit comprising a support, means mounting said support for pivotal movement, said support having a terminal edge portion remote from said mounting means, said terminal edge portion being in the form of a plurality of fingers spaced transversely of said support, at least certain of said fingers having terminal stop means for positioning a starter web, and hold down means carried by said support for holding a new web on said support, said mounting means being supported in an elevated position by a machine frame; and a web support spindle for supporting a new web in roll form, support means for supporting said spindle from said frame in an elevated position, said support means comprising a fixed support for releasably receiving one end of said spindle and a support arm rigidly connected to the other end of said spindle, first hinge means connecting said support arm to said frame for swinging movement of said spindle from a horizontal operative position to a vertical intermediate position, said support arm being of a two piece construction and second hinge means arranged parallel to said first hinge means hingedly connecting said support arm pieces together for the relative movement thereof to a position wherein said spindle is in a horizontal web round receiving position to one side of said frame and materially below said horizontal operative position.

Claim 12

For use in a web splicer, a make-ready unit comprising a support, means mounting said support for pivotal movement, said support having a terminal edge portion remote from said mounting means, said terminal edge portion being in the form of a plurality of fingers spaced transversely of said support, at least certain of said fingers having terminal stop means for positioning a starter web, and hold down means carried by said support for holding a new web on said support, said mounting means being supported in an elevated position by a machine frame; and a web support spindle for supporting a new web in roll form, support means for supporting said spindle from said frame in an elevated position, said support means comprising a fixed support for releasably receiving one end of said spindle and a support arm rigidly connected to the other end of said spindle, first hinge means connecting said support arm to said frame for swinging movement of said spindle from a horizontal operative position to a vertical intermediate position, said support arm being of a two piece construction and second hinge means arranged parallel to said first hinge means hingedly connecting said support arm pieces together for the relative movement thereof to a position wherein said spindle is in a horizontal web round receiving position to one side of said frame and materially below said horizontal operative position.

Claim 13

The device of claim 10 together with latch means carried by one of said support arm pieces and engageable with the other of said support arm pieces for selectively rendering said second hinge means inoperative.

Claim 14

A web feed and splicing arrangement comprising a pair of cooperating feed rolls defining a continuously formed nip, first and second web support means for mounting webs in roll form on opposite sides of said nip, and web splicing means mounted adjacent said feed rolls for directing a web splice directly in said nip, said web splicing means including a separate splice forming unit individually associated with each of said feed rolls, each splice forming unit being in the form of a make ready unit comprising a support, means mounting said support for pivotal movement, said support having a terminal edge portion remote from said mounting means, said terminal edge portion being in the form of a plurality of fingers spaced transversely of said support and forming a longitudinal extension of said support, at least certain of said fingers having terminal stop means remote from said support for longitudinally positioning a starter web, and hold down means carried by said support for holding a new web on said support.

Claim 15

A web feed and splicing arrangement comprising a pair of cooperating feed rolls defining a continuously formed nip, first and second web support means for mounting webs in roll form on opposite sides of said nip, and web splicing means mounted adjacent said feed rolls for directing a web splice directly in said nip, said web splicing means including a separate splice forming unit individually associated with each of said feed rolls, each splice forming unit being in the form of a make ready unit comprising a support, means mounting said support for pivotal movement, said support having a terminal edge portion remote from said mounting means, said terminal edge portion being in the form of a plurality of fingers spaced transversely of said support and forming a longitudinal extension of said support, at least certain of said fingers having terminal stop means remote from said support for longitudinally positioning a starter web, and hold down means carried by said support for holding a new web on said support.
