Abstract
Abstract Apparatus is provided for applying securing tabs to absorption products such as diapers, sanitary towels, compresses and the like, conveyed successively as single units in a continuous path, the securing tabs being coated on one side with adhesive to which is attached an easily removable protective paper, which comprises conveying the securing tabs continuously and successively in two parallel rows, on each side of the path of the absorption products, substantially at a right angle to the path of absorption products, at a level higher than and parallel to the path of absorption products, and with the gummed surfaces turned downward; removing the protective paper from the halves of the securing tabs in each row that face the parallelly fed row of securing tabs; separating each securing tab from its respective row of securing tabs; and pressing the separated securing tabs in pairs onto the absorption products, with the halves coated with protective paper turned away from each other, and extending beyond the corresponding edge of the respective absorption products transversely to the conveying direction for the absorption products.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
192 words
Apparatus for applying securing tabs to absorbent products conveyed successively as single units attached together in a long strip, said securing tabs being coated on one side with adhesive and having an easily removable protective sheet on the adhesive, comprising, in combination, means for conveying a long strip of absorbent products in one direction; means for conveying securing tabs having an adhesive on one surface continuously and successively in two parallel rows on each side of the strip of absorbent products, each row moving in a direction substantially at a right angle to the strip, at a level higher than and parallel to the strip, with adhesive surfaces turned downward; means for removing a portion of the protective sheet from the adhesive surfaces of the securing tabs in each row to expose such portions of the adhesive surface; means for separating each securing tab from its respective row of securing tabs; and means for applying the exposed adhesive surfaces of the separated securing tabs in pairs to the absorbent products and the portion of the tabs still having a protective sheet thereon extending beyond the corresponding edge of the respective absorbent products.
Claim 2
Dependent Claim
192 words
Apparatus for applying securing tabs to absorbent products conveyed successively as single units attached together in a long strip, said securing tabs being coated on one side with adhesive and having an easily removable protective sheet on the adhesive, comprising, in combination, means for conveying a long strip of absorbent products in one direction; means for conveying securing tabs having an adhesive on one surface continuously and successively in two parallel rows on each side of the strip of absorbent products, each row moving in a direction substantially at a right angle to the strip, at a level higher than and parallel to the strip, with adhesive surfaces turned downward; means for removing a portion of the protective sheet from the adhesive surfaces of the securing tabs in each row to expose such portions of the adhesive surface; means for separating each securing tab from its respective row of securing tabs; and means for applying the exposed adhesive surfaces of the separated securing tabs in pairs to the absorbent products and the portion of the tabs still having a protective sheet thereon extending beyond the corresponding edge of the respective absorbent products.
Claim 3
Dependent Claim
76 words
An apparatus according to claim 1, in which the means for applying the securing tabs to the absorbent products comprises a reel for storing rolled-up strips of securing tabs parallel to each other; means for feeding the strips of securing tabs from the reel in two parallel rows towards the strip of absorbent products, and vertically movable applicator means for retaining separated securing tabs and for pressing said tabs onto absorbent products of the long strip.
Claim 4
Dependent Claim
39 words
An apparatus according to claim 2, in which the means for removing the protective sheet on the securing tabs comprises two rotatable rolls positioned adjacent each other to form a nip, and in parallel relationship to the storage reel.
Claim 5
Dependent Claim
62 words
An apparatus according to claim 2, in which the means for feeding the strips of securing tabs comprises two rotatable rolls positioned adjacent each other at a higher level than the protective means for stripping sheet from the tabs and in parallel relationship to the storage reel and between the reel and the means for conveying the long strip of absorbent products.
Claim 6
Dependent Claim
53 words
An apparatus according to claim 1, in which the means for conveying a strip of absorbent products comprises a cylindrical drum mounted for rotation in the vertical plane, and means within the drum for applying a suction force from within the drum surface to retain the strip of absorbent products on the drum.
Claim 7
Dependent Claim
37 words
An apparatus according to claim 5, in which the drum is provided with a row of recesses in the cylindrical surface thereof, each of which recesses is adapted to receive one absorbent product unit of the strip.
Claim 8
Dependent Claim
21 words
