Abstract
Abstract A compression strapping machine for binding large bundles, such as a stack of plywood, includes a hopper fed dispensing device for edge protectors capable of firmly and accurately positioning the protectors between the bundle and the encircling strap for protecting the edges of the bundle from damage. The device includes a leaf spring and dashpot movable with the dispenser for controllably positioning a protector support in alignment with a delivery station, the support receiving and retaining the protector in position prior to tightening of the strapping. The dispensing device is laterally movable to accommodate packages of different width.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
153 words
A feeder assembly for edge protectors well suited for use in a compression strapping machine defining a strapping station and having a pressure platen reciprocally movable toward and away from a bundle positioned within said station, including a feeder having a delivery station for systematically receiving edge protectors to be dispensed, a stripping station immediately adjacent said delivery station for receiving individual edge protectors from said delivery station, an operator for selectively driving an edge protector from the delivery station toward the stripping station for positioning the edge protector in spaced conforming relationship to the edge of the bundle receiving the protector and releasable retaining means within said stripping station for abuttably receiving an edge protector driven from the delivery station by the operator and firmly retaining the delivered protector within the stripping station in spaced conforming relationship to the edge of the bundle until stripped therefrom by the strapping securing said bundle.
Claim 2
Dependent Claim
153 words
A feeder assembly for edge protectors well suited for use in a compression strapping machine defining a strapping station and having a pressure platen reciprocally movable toward and away from a bundle positioned within said station, including a feeder having a delivery station for systematically receiving edge protectors to be dispensed, a stripping station immediately adjacent said delivery station for receiving individual edge protectors from said delivery station, an operator for selectively driving an edge protector from the delivery station toward the stripping station for positioning the edge protector in spaced conforming relationship to the edge of the bundle receiving the protector and releasable retaining means within said stripping station for abuttably receiving an edge protector driven from the delivery station by the operator and firmly retaining the delivered protector within the stripping station in spaced conforming relationship to the edge of the bundle until stripped therefrom by the strapping securing said bundle.
Claim 3
Dependent Claim
39 words
The feeder assembly of claim 1 wherein the feeder includes damping means associated with the retaining means for controlling the movement of the retaining means under the driving force of the protector during positioning thereof in the stripping station.
Claim 4
Dependent Claim
56 words
The feeder assembly of claim 1 wherein the feeder includes biasing means for urging the retaining means toward the delivery station for receiving and retaining protectors driven from the delivery station and damping means for damping the movement of the retaining means under the driving force of the protector during positioning thereof in the stripping station.
Claim 5
Dependent Claim
60 words
The feeder assembly of claim 1 wherein the feeder includes a magazine for edge protectors communicating with the delivery station for continuously supplying edge protectors thereto and the operator includes a reciprocating slide movable transversely of the magazine along the delivery station for delivering a protector to the stripping station and maintaining contact therewith until the protector is stripped therefrom.
Claim 6
Dependent Claim
48 words
The feeder assembly of claim 1 wherein the releasable retaining means includes a pad aligned with the delivery station and configured to receive an edge protector and biasing means urging the pad toward the operator for cooperating with the operator in retaining the protector in the stripping station.
Claim 7
Dependent Claim
64 words
The feeder assembly of claim 1 wherein the feeder includes a magazine for edge protectors communicating with the delivery station for continuously supplying edge protectors thereto, biasing means mounted on the magazine for urging the retaining means toward the delivery station and a dashpot connected to the biasing means for controlling the movement of the retaining means under the driving force of the protector.
Claim 8
Dependent Claim
60 words
The feeder assembly of claim 1 including a support member for the feeder mounted on the platen for limited movement transversely of the bundle within the strapping station, said support member including sensing and positioning means for sensing the location of the bundle and imparting said transverse movement to the assembly for positioning thereof adjacent the edge of the bundle.
Claim 9
Dependent Claim
20 words
The feeder assembly of claim 7 wherein said sensing and positioning means includes a cam portion cooperating with said bundle.
Claim 10
Dependent Claim
56 words
The feeder assembly of claim 7 wherein the feeder includes biasing means for urging the retaining means toward the delivery station for receiving and retaining protectors driven from the delivery station and damping means for damping the movement of the retaining means under the driving force of the protector during positioning thereof in the stripping Station.
Claim 11
Dependent Claim
74 words
The feeder assembly of claim 1 in combination with a compression strapping machine having a reciprocably movable pressure platen, the assembly being movable with the platen and transversely thereto to accommodate bundles of different dimension, said assembly including biasing means and inclined cam surface for contacting the edges of the bundle within the strapping station and driving the assemblies against the bias of said biasing means upon movement of the platen toward the bundle.
