Claim 6

Dependent Claim 87 words

A paper stuffer selectively for positioning cut paper strips between convolutions of a loosely wound strip coil or the like on a driven recoiler comprising paper feed means operative to direct the paper into the nip of the outer convolution of the coil and severing means between the coil and the feed means, means to place the paper between said feed means and coil in tension, and means responsive to a preselected tension of such paper being obtained to cause the severing means to cut the paper.

Claim 7

Dependent Claim 38 words

The paper stuffer of claim 3 wherein the paper feed means and severing means are mounted in a pivotal arm that is angularly adjustable tangentially to align the paper feed with the periphery of the slit strip coil.

Claim 8

Dependent Claim 42 words

Claim 9

Dependent Claim 33 words

The paper stuffer of claim 3 wherein the paper feed means includes driven pinch rollers and a paper supply coil, the pinch rollers being between such supply coil and the paper severing means.

Claim 10

Dependent Claim 45 words

The machine of claim 6 further including power means selectively tO drive one of the pinch rollers for dispensing paper, such one roller being disengaged from the power means by a clutch and held against rotation by a brake when paper is not being fed.

Claim 11

Dependent Claim 41 words

The paper stuffer of claim 7 wherein the power means clutch and brake are controlled by an electric circuit operative upon actuation continuously to run said power means during selective energization of the brake and clutch coils according to machine function.

Claim 12

Dependent Claim 63 words

Claim 13

Dependent Claim 94 words

The paper stuffer of claim 9 wherein the arbor means includes a paper spool shaft, which is spring loaded into operative position but adapted for movement against said spring for paper replacement, and a spring loaded side plate urged against a lateral surface of the paper coil, said side plate having a pin and slot connection with said core to preclude relative rotation therebetween while allowing axial movement under spring bias for said side plate, whereby paper coils of varying widths may be received in said arm for rotation on said core without slippage.

Claim 14

Dependent Claim 36 words
