Automatic transfer system
First Claim
1. An automatic transfer system for parallel processing a group of clips of stacked laminar products comprising:
- (a) a machine frame having;
(i) a base, and(ii) advancing means mounted on said base having reciprocating means carrying selectively projectable pins for periodically advancing a group of clips; and
(b) a clip spreading station having;
(i) spreader means for increasing clip-to-clip spacing transverse to the direction of advance of said advancing means such that the clips in a group are more widely spaced upon leaving than upon entering said system.

Abstract
A machine for parallel processing a group of clips of stacked interfolded paper sheets having a base, a reciprocating table carrying projectable pins for advancing the group of clips, a clip spreading station for increasing clip-to-clip spacing transverse to the direction of advance of the reciprocating table, a pre-compression station for compressing the clips to a uniform height, a rotation station for selectively rotating each clip 90° length to width, and a folding station having selectively operable opposed blades parallel to the width for forming each clip into a generally U-shaped configuration to fit within a cube-like package.

13. A method of longitudinally advancing and positioning successive groups of clips of stacked laminar products from an input station to an output position and transversely spreading the clips in each group by moving said clips in groups from station to station comprising:
-
(a) reciprocating a table in a direction of advance from a first position to a second position such that said table stops adjacent a plurality of stations at each of said first and second positions; (b) reciprocating a plurality of pins generally orthogonal to said table such that; (i) said pins project from the plane of said table when said table moves forward in the direction of advance, and (ii) said pins are recessed below the plan of said table when said table moves backward against the direction of advance; and (c) spreading the clips in a particular group while that group is at a spreader station such that the clip-to-clip separation in a direction transverse to the direction of advance is increased. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)

22. A machine for transferring and processing clips of interfolded paper sheets comprising:
-
(a) a base; (b) transfer means adjustably mounted on said base for advancing a plurality of clips from station to station; (c) an input station mounted on said base for receiving a plurality of adjacent clips; (d) a pre-compression station mounted on said base for reducing the height of said clips below that at said input station; (e) a spreader station mounted on said base for providing separation among said plurality of clips; (f) a rotation station mounted on said base for selectively rotating each clip then at that station 90°
; and(g) a forming station mounted on said base for selectively forming each clip then at that station into a U-shaped configuration. - View Dependent Claims (23, 24, 25, 26)

27. An automatic transfer system for parallel processing a group of clips of stacked laminar products comprising:
-
(a) a machine frame having; (i) a base, and (ii) advancing means mounted on said base for periodically advancing a group of clips; and (b) a clip spreading station having; (i) spreader means for increasing clip-to-clip spacing transverse to the direction of advance of said advancing means such that the clips in a group are more widely spaced upon leaving than entering said system wherein said spreader means comprises a plate for each clip having a surface texture with relatively lower friction in the direction of advance and a relatively higher friction transverse to the direction of advance. - View Dependent Claims (28, 29, 30, 31, 32, 33, 34, 35, 36, 37)
