Abstract
Abstract A device for forming a package of impregnated tissues from a continuous roll of a lightweight fiber material such as a tissue comprises means for feeding the tissue for slitting longitudinally into one or more lengths of tissue and then for perforating the lengths at definite fixed intervals across the width thereof. The perforated lengths are separated and fed separately through folding gauges where they are parted with one or more folds and one or more of these lengths are fed simultaneously into a bath for impregnating the tissue with a liquid substance such as a face cleaning solvent of a type which is incorporated in the known wash tissues. The impregnated tissues are then fed continuously and directly into guide tubes and thereafter transferred directly into packing containers into which they are stuffed. The stuffing mechanism comprises an arrangement for feeding the respective continuous lengths of the impregnated tissue into a stuffing container to accumulate a compacted pile and thereafter transferring the pile into a packing container. The pile is formed and compacted merely by feeding the tissue at high speed into the stuffing container in which the tissues become packed.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
182 words
A method of forming packages with a continuous strip of separate liquid impregnated tissues which are separated from each other by perforations, comprising feeding a continuous web of lightweight material such as a tissue through a continuous feed path, perforating the web to form perforation lines extending thereacross at spaced locations along the length thereof and to form individual separable tissues between the perforations, directing the tissues interconnected by perforation lines into a treatment bath, moving the treated tissues out of the treatment bath while they are still interconnected by the perforations, and feeding the web of connected treated tissues into a stuffing container whereby said web is folded as it is fed into said stuffing container and wherein said web of connected tissues are fed into a stuffing container to accumulate a quantity of said connected tissues equivalent to the amount adapted to be packed in a packing container, severing the web of accumulated tissues from the remaining length of said web of tissues, and forcing the accumulated tissues from the stuffing container and into a packing container disposed adjacent thereto.
Claim 2
Independent Claim
182 words
A method of forming packages with a continuous strip of separate liquid impregnated tissues which are separated from each other by perforations, comprising feeding a continuous web of lightweight material such as a tissue through a continuous feed path, perforating the web to form perforation lines extending thereacross at spaced locations along the length thereof and to form individual separable tissues between the perforations, directing the tissues interconnected by perforation lines into a treatment bath, moving the treated tissues out of the treatment bath while they are still interconnected by the perforations, and feeding the web of connected treated tissues into a stuffing container whereby said web is folded as it is fed into said stuffing container and wherein said web of connected tissues are fed into a stuffing container to accumulate a quantity of said connected tissues equivalent to the amount adapted to be packed in a packing container, severing the web of accumulated tissues from the remaining length of said web of tissues, and forcing the accumulated tissues from the stuffing container and into a packing container disposed adjacent thereto.

Claim 6
Independent Claim
112 words
An apparatus for stuffing tissue into containers comprising a stuffing container having a bottom with a closable flap, movable between a closed and opened position, tissue feed means for directing a continuous length of interconnected tissues separated by perforations into said stuffing container, and stuffing means located adjacent said stuffing container and being movable through said stuffing container to force the accumulated tissues in said stuffing container to open said bottom flap, whereby said accumulated tissues are adapted to be transferred to a packing container, said stuffing means being movable to direct the material of said stuffing container through the opening when said bottom flap is open and into said packing container.
Claim 7
Dependent Claim
73 words
An apparatus according to claim 4, wherein said tissue feed means includes a pair of rotatable press rollers at a spaced location from said stuffing container and a pair of rotatable stuffing rollers adjacent said press rollers, the tissue being fed between said press rollers and said stuffing rollers, said press rollers being stopable to cause the severance of the tissue from the remaining length by the continued rotation of said stuffing rollers.
Claim 8
Dependent Claim
