Abstract
Abstract An apparatus for inserting contour rods into the pockets of double-web mats for storage-battery electrodes comprises a contour-rod magazine with dispensing means for releasing one rod at a time. A spreader device opens the pockets of the mat. Catch and guide means then engage the released rod and partially insert it into a pocket then spread open. Further transport means engage the partially inserted rod and completely shove it into the mat pocket. A control mechanism operates to actuate the abovementioned component devices of the apparatus in the sequence described. Preferably two rod inserting apparatus are arranged on opposite sides of the double-web mat for simultaneously inserting respective contour rods from opposite sides into the pockets.

Claim 3
Dependent Claim
51 words
In apparatus according to claim 1, said rod drive means comprising catch and guide means disposed adjacent said dispensing means and engageable with the released rod for partially inserting it into said spread open pocket, and rod transport means engageable with said released rod for completely shoving it into said pocket.
Claim 4
Dependent Claim
34 words
Apparatus according to claim 2, comprising sequence control means connected with said dispensing means and said spreader device and said rod drive means for controlling them to cyclically operate in the repetitive releasing-spreading-shoving sequence.
Claim 5
Dependent Claim
86 words
Apparatus according to claim 1, comprising a mat-supporting table on which the mat is longitudinally advanceable with the mat pockets extending in a direction transverse to the mat advancing direction, said apparatus being arranged beside the mat advancing path of said table, said dispensing means of said magazine comprising an elongated slot dimensioned to let only one rod pass through at a time, said slot extending parallel to said transverse direction so that the dispensed rods are aimed substantially toward respective pocket openings of the mat.
Claim 6
Dependent Claim
45 words
In apparatus according to claim 4, said dispensing means comprising conveyor worms rotatable at opposite ends respectively of said elongated slot and having respective worm gear turns engageable by the ends of a rod for controlling the individual dispensation of the rods from said magazine.
Claim 7
Dependent Claim
64 words
In apparatus according to claim 4, said rod drive means comprising a catch device engageable with the rear end of a rod released by said dispensing device and movable toward said mat path of said table for partly shoving the rod into the mat pocket, and driven guide rollers engageable with the rod for seizing the rod and shoving it further into the pocket.
Claim 8
Dependent Claim
42 words
In apparatus according to claim 6, said guide rollers comprising a pair of profiled rollers whose profile corresponds to the cross-sectional shape of the rods, and a hinged supporting roller also engageable with the rod between the rod-engaging localities of said pair.
Claim 9
Dependent Claim
49 words
In apparatus according to claim 2, said rod transport means comprising a pair of upper and lower rollers, said upper roller being externally threaded and having a screw pitch that is an integral multiple of the pocket width of the mat, said lower roller having a glide-resistant peripheral surface.
Claim 10
Dependent Claim
25 words
In apparatus according to claim 8, the first thread turn of said upper roller having a cut-out portion extending along one-half of the roller periphery.
Claim 11
Dependent Claim
56 words
In apparatus according to claim 4, said spreader device comprising a bearing block, a pair of rocker arms pivoted on said bearing block, one of said rocker arms being above the mat locality of said table, said other rocker arm being below said locality, said rocker arms being provided with pressure faces on the mat-facing side.
Claim 12
Dependent Claim
37 words
In apparatus according to claim 3, said control means comprising a rotatable control cam, cam followers engaging said cam and connected to said respective rocker arms for controlling their operation in dependence upon rotation of said cam.
Claim 13
Dependent Claim
62 words
Apparatus according to claim 11, comprising a spring link which interconnects said two followers to force them against said cam, and a pair of retainer levers situated on the two sides respectively of each of said rocker arms and interconnected for conjoint movement, said two retainer levers and said rocker arm intermediate said two retainer levers having a fulcrum axis in common.
Claim 14
Dependent Claim
66 words
In apparatus according to claim 12, said two rocKer arms having respect prismatic portions pointing toward each other, each pair of said retainer levers having ends adjacent to said rocker-arm prisms with lateral faces of said rocker-arm prisms parallel to lateral faces of said retainer-lever ends, said lateral faces of said retainer-lever ends having a rougher surface than the adjacent parallel faces of said rocker-arm prisms.
