Abstract
Abstract An apparatus to assemble and weld corrugated metal ribbon to form a honeycomb pad. A horizontal feeding mechanism is provided by a pair of clamping arrangements one mounted on a stationary base and one mounted on a horizontally movable carriage which moves the one clamping arrangement toward and away from the other. The movable carriage has mounted thereon a ribbon pressure pad and an alignment pin. An air cylinder on said carriage moves the ribbon pressure pad and alignment pin toward the corrugated ribbons until the pointed alignment pin is projecting into a cell between the ribbons and the ribbons are oriented. The air cylinder moves the pressure pad into the resilient contact with the ribbons holding them in a flat uniform condition while a carriage mounted welding electrode is moved into contact with the ribbons for welding them together.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
173 words
Honeycomb ribbon pad manufacturing apparatus comprising a base, a first clamping means mounted on said base and adapted to grip and hold the pad relative to the base, a carriage movably mounted on said base for movement toward and away from said first clamping means, a means movably supporting said carriage for movement in a horizontal direction, a second clamping means mounted on said carriage and adapted to grip the ribbons of said pad and hold them relative to said carriage, a welding electrode mounted on said carriage and movable into and out of engagement with said ribbons, a means mounting said electrode to said carriage for moving said electrode in said horizontal direction with said carriage, a means mounting said second clamping means to said carriage for moving said pad in said horizontal direction with said carriage, a means for releasing said first clamping means throughout the period of movement of said carriage, and means for aligning and holding the ribbons relative to one another and in predetermined relation to said electrode.
Claim 2
Dependent Claim
173 words
Honeycomb ribbon pad manufacturing apparatus comprising a base, a first clamping means mounted on said base and adapted to grip and hold the pad relative to the base, a carriage movably mounted on said base for movement toward and away from said first clamping means, a means movably supporting said carriage for movement in a horizontal direction, a second clamping means mounted on said carriage and adapted to grip the ribbons of said pad and hold them relative to said carriage, a welding electrode mounted on said carriage and movable into and out of engagement with said ribbons, a means mounting said electrode to said carriage for moving said electrode in said horizontal direction with said carriage, a means mounting said second clamping means to said carriage for moving said pad in said horizontal direction with said carriage, a means for releasing said first clamping means throughout the period of movement of said carriage, and means for aligning and holding the ribbons relative to one another and in predetermined relation to said electrode.
Claim 3
Dependent Claim
67 words
The honeycomb ribbon pad manufacturing apparatus of claim 1 wherein said means for aligning and holding comprises an alignment pin formed to fit vertically into a cell between the ribbons of said pad, said alignment pin being mounted on said carriage and projecting through the second clamping means whereby said pin is moved into a cell before said second clamping means engages the ribbons defining said cell.
Claim 4
Dependent Claim
75 words
The honeycomb ribbon pad manufacturing apparatus of claim 2 wherein said welding electrode is moved into contact with said ribbon by a spring acting between said carriage and said electrode, said apparatus including cam means movably mounted on said carriage for limiting and determining the extent of movement of said electrode against said ribbon as forced by said spring, and means for moving said cam between an electrode projected position and an electrode retracted position.
Claim 5
Dependent Claim
71 words
The honeycomb ribbon pad manufacturing apparatus of claim 2 wherein said carriage and second clamping means additionally comprises an anvil fixed to said carriage and adapted to support said honeycomb pad, a fixed guide means secured to said carriage and providing a limit for one side of said honeycomb ribbon pad, and a spring biased guide member mounted on said carriage and acting to hold said pad against said guide means.
Claim 6
Dependent Claim
45 words
The honeycomb ribbon pad manufacturing apparatus of claim 4 wherein: said first clamping means has a movable piston rod with a lever mounted thereto, said lever has a ribbon clamp lockingly engageable with said ribbons as said piston rod forces said lever towards said base.
Claim 7
Dependent Claim
75 words
The honeycomb ribbon pad manufacturing apparatus of claim 4 wherein: said carriage has upper and lower portions horizontally movable as a unit with said ribbons normally disposable therebetween, said carriage has a pair of cylinder mOtors with one motor operable to control the vertical distance between said portions and the other motor operable to raise and lower said alignment pin; and, said second clamping means has a horizontal plate springingly suspended form said upper portion.
Claim 8
Dependent Claim
25 words
The honeycomb ribbon pad manufacturing apparatus of claim 6 wherein: said upper portion has stop means limiting the upward vertical movement of said horizontal plate.
Claim 9
Dependent Claim
32 words
The honeycomb ribbon pad manufacturing apparatus of claim 7 wherein: said upper portion has means therein adjustable to control the vertical positioning of said alignment pin with respect to said horizontal plate.
Claim 10
Dependent Claim
27 words
The honeycomb ribbon pad manufacturing apparatus of claim 1 wherein: said first clamping means is operable to release said pad prior to horizontal movement of said carriage.
