Abstract
Abstract A feed mechanism for packing material such as carton blanks is disclosed. Blanks are arranged in a hopper where they are stacked between a pair of vertical members having their lower edges spaced above a support table for advancement of the bottommost blank by a shuttle into the feeding means. The spacing between one of the vertical members above the support is greater than the thickness of the blank and less than twice the thickness thereof and during feed movement a roller is biased against the feed blank to urge it against the bottom of a member. Thus a gate is provided between the bottom of a vertical member and the support.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
167 words
In a feeding mechanism for delivering packaging forming material, such as folded carton blanks, without jamming, from a hopper toward a carton erecting mechanism, the combination of: (a) a hopper containing a plurality of folded carton blanks arranged in a stack; (b) support means located adjacent said hopper and having a surface extending in a plane generally parallel to the plane of movement of a blank moving means; (c) a gate member positioned at the discharge end of said hopper and having an edge spaced from said support means; (d) said blank moving means engageable with the outermost blank of said stack for moving said blank over said support means toward said gate member; (e) biased metering means located below and adjacent said gate member edge for engaging the outside of said outermost blank only, as it passes by said gate member, and sufficiently biased to urge it snugly against said edge to prevent an adjacent blank from entering between said gate member and said outermost blank.
Claim 2
Dependent Claim
167 words
In a feeding mechanism for delivering packaging forming material, such as folded carton blanks, without jamming, from a hopper toward a carton erecting mechanism, the combination of: (a) a hopper containing a plurality of folded carton blanks arranged in a stack; (b) support means located adjacent said hopper and having a surface extending in a plane generally parallel to the plane of movement of a blank moving means; (c) a gate member positioned at the discharge end of said hopper and having an edge spaced from said support means; (d) said blank moving means engageable with the outermost blank of said stack for moving said blank over said support means toward said gate member; (e) biased metering means located below and adjacent said gate member edge for engaging the outside of said outermost blank only, as it passes by said gate member, and sufficiently biased to urge it snugly against said edge to prevent an adjacent blank from entering between said gate member and said outermost blank.
Claim 3
Dependent Claim
22 words
In a mechanism as defined in claim 1, wherein said metering means adjacent said gate member surface includes a pressure biased roller.
Claim 4
Dependent Claim
16 words
In a mechanism as defined in claim 2, wherein said roller is biased by spring means.
Claim 5
Dependent Claim
20 words
In a mechanism as defined by claim 3, wherein said spring means includes a spring actuated arm carrying said roller.
Claim 6
Dependent Claim
18 words
In a mechanism as defined in claim 4, wherein said arm is pivotally mounted on said support means.
Claim 7
Dependent Claim
26 words
In a mechanism as defined in claim 1, where said blank moving means includes a shuttle movable adjacent at least a part of said support means.
Claim 8
Dependent Claim
18 words
In a mechanism as defined in claim 1, wherein said support means is located directly under said hopper.
