Abstract
Abstract An apparatus and method for compacting and strapping cylindrical product coils. Each coil is transported to a position between spaced oppositely disposed compacting elements. The compacting elements, which are movable in a direction parallel to the coil axis, are then advanced symmetrically towards each other to axially compact the coil. Thereafter, strapping devices are operatively positioned and actuated to apply a plurality of circumferentially spaced retaining straps to the coil while the coil remains axially compacted between the compacting elements. The compacting elements and strapping devices are then returned to their inoperative positions, and the compacted strapped coil is removed to another location.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
136 words
Apparatus for compacting and strapping a cylindrical product coil comprising: transport means for carrying the coil along a given path, said transport means including an elongated member extending axially through the coil with the coil being substantially free from axial restraint while on said member, compacting means for axially compacting the coil on said transport means while said elongated member remains axially inserted through the coil, said compacting means including compacting elements arranged to engage opposite ends of the coil, said compacting means further including drive means for symmetrically moving each of said compacting elements towards the center of said path so as to axially compact the coil therebetween; and, strapping means for simultaneously applying retaining straps to the coil at a plurality of circumferentially spaced locations while the coil remains compacted between said compacting elements.
Claim 2
Dependent Claim
136 words
Apparatus for compacting and strapping a cylindrical product coil comprising: transport means for carrying the coil along a given path, said transport means including an elongated member extending axially through the coil with the coil being substantially free from axial restraint while on said member, compacting means for axially compacting the coil on said transport means while said elongated member remains axially inserted through the coil, said compacting means including compacting elements arranged to engage opposite ends of the coil, said compacting means further including drive means for symmetrically moving each of said compacting elements towards the center of said path so as to axially compact the coil therebetween; and, strapping means for simultaneously applying retaining straps to the coil at a plurality of circumferentially spaced locations while the coil remains compacted between said compacting elements.
Claim 3
Dependent Claim
71 words
The apparatus as claimed in claim 1 wherein said transport means is comprised of a hook carrier having a plurality of hooks movable along said path at a level above that of said compacting means, each hook being adapted to axially support a cylindrical product coil, and means for lowering a hook overlying said compacting means to a level such that the coil supported thereon is positioned between said compacting elements.
Claim 4
Dependent Claim
41 words
The apparatus as claimed in claim 2 wherein said drive means include at least one double-acting hydraulic cylinder connected to each cOmpacting element, the said compacting elements being movably mounted on rail members extending in a direction transverse to said path.
Claim 5
Dependent Claim
117 words
Apparatus for compacting and strapping cylindrical product coils, said apparatus comprising: a pair of spaced compacting elements located on opposite sides of and beneath a given path; transport means including a hook for carrying a coil along said path to a position overlying the space between said compacting elements; means for lowering said hook to position the coil between said compacting elements; means for symmetrically advancing said compacting elements towards the center of said path so as to axially compact the coil without shifting the center of gravity of the coil in relation to said path, and, means for applying a plurality of retaining straps to the coil while the coil remains compacted between said compacting elements.
Claim 6
Dependent Claim
117 words
Apparatus for compacting and strapping cylindrical product coils, said apparatus comprising: a pair of spaced compacting elements located on opposite sides of and beneath a given path; transport means including a hook for carrying a coil along said path to a position overlying the space between said compacting elements; means for lowering said hook to position the coil between said compacting elements; means for symmetrically advancing said compacting elements towards the center of said path so as to axially compact the coil without shifting the center of gravity of the coil in relation to said path, and, means for applying a plurality of retaining straps to the coil while the coil remains compacted between said compacting elements.
Claim 7
Dependent Claim
119 words
Coil-handling apparatus comprising in combination: a hook for transporting a coil, said hook extending axially through the coil with the coil being substantially free from axial restraint while on said hook; compacting means for compacting said coil in a manner such that the position of the center of gravity of said coil remains substantially unchanged relative to said hook; and, means for strapping said coil simultaneously at a plurality of circumferentially spaced points while the coil remains compacted by said compacting means, whereby following the compacting and strapping operation, the attitude of said hook remains substantially unaffected because the position of the center of gravity of the coil has not been significantly shifted during the compacting and strapping operation.
Claim 8
Dependent Claim
119 words
Coil-handling apparatus comprising in combination: a hook for transporting a coil, said hook extending axially through the coil with the coil being substantially free from axial restraint while on said hook; compacting means for compacting said coil in a manner such that the position of the center of gravity of said coil remains substantially unchanged relative to said hook; and, means for strapping said coil simultaneously at a plurality of circumferentially spaced points while the coil remains compacted by said compacting means, whereby following the compacting and strapping operation, the attitude of said hook remains substantially unaffected because the position of the center of gravity of the coil has not been significantly shifted during the compacting and strapping operation.
Claim 9
Independent Claim
114 words
A method of compacting and strapping a product coil comprising the steps of: transporting the coil along a path transverse to the coil axis to a position overlying a pair of spaced compacting elements; lowering the coil to a position between said elements; axially compacting the coil by symmetrically advancing said elements towards one another, the said axial compaction taking place without shifting the center of gravity of the coil relative to said path; simultaneously applying a plurality of circumferentially spaced retaining straps to the coil while the coil remains axially compacted between said elements; and, thereafter retracting the compacting elements prior to transporting the compacted strapped coil along said path to another location.
Claim 10
Independent Claim
114 words
