Abstract

Abstract Abstract of the Disclosure Apparatus for forming honeycomb material comprising a bonding station for continuously secur-ing together an even numbered plurality of superim-posed webs of flexible sheet material, such as paper, on lines extending longitudinally of the webs and spaced transversely across the webs at substantially equal intervals to form a composite web. A second adhesive station applies stripes of adhesive on an outside face on one of the webs constituting one out-side face of the composite web, these outer stripes extending longitudinally of the composite web and each stripe being positioned intermediate the lines on the inside face of the one web securing this one web to the remaining webs of the composite web. A web feed is intermittently operable in cycles to feed forward an increment of the composite web beyond a reference line a predetermined distance and n intermittently operable drive drives the feed through a cycle to feed forward this increment of predetermined length with a dwell be-tween successive cycles. Segmenting blades are oper-able during each dwell for segmenting this increment from the composite web and for stacking the resulting segments in a stack with the adhesive stripes on the one outside face of each segment adapted to engage the other outside face of an adjacent segment in the stack. A press compresses the stack of segments for bonding the segments together so as to form the honey-comb material. A method of manufacturing honeycomb material is also disclosed.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 335 words
Apparatus for forming honeycomb material comprising: means for securing together an even numbered plurality of super-imposed webs of flexible sheet material to form a composite web by forming adhesive lines between opposite web faces extending longitudinally of the webs and spaced transversely across the webs and by forming adhesive stripes on one outside face of the composite web; feed means engaging the composite web for advanc-ing a predetermined length of composite web past a reference line during an advancing phase and for arresting the movement of the predetermined length during a dwell phase; the feed means com-prising at least one web advancing roller engaging a side of the web, a continuously rotating drive member, a link operatively coupled with the drive member for transforming the rotating mo-tion of the drive member into an oscillating motion for the link, and one way clutch means operatively coupling the link and the roller for rotating the roller through an angle of rotation during the advancing phase when the link oscillates in one direction and for arresting the rotation of the roller during the dwell phase when the link oscillates in the other direction; means defining a pivot axis for the link; adjustment means operatively coupled with the feed means for changing during normal operation of the feed means the predetermined length of composite web advanced by the feed means which includes crank arm means connected with the clutch means, bar means pivotally secured to the link and crank arm means, and means operatively connected with the link and the bar means for changing the distance between the pivot axis and the point at which the bar means is pivotally connected to the link to cause a corres-ponding change in the angle through which the roller is rotated; means for severing the predetermined length of composite web along the reference line during the dwell phase to form composite web segments; and means for stacking the segment so that the segments are secured to each other by the adhesive stripes.
Claim 2
Dependent Claim 335 words
Apparatus for forming honeycomb material comprising: means for securing together an even numbered plurality of super-imposed webs of flexible sheet material to form a composite web by forming adhesive lines between opposite web faces extending longitudinally of the webs and spaced transversely across the webs and by forming adhesive stripes on one outside face of the composite web; feed means engaging the composite web for advanc-ing a predetermined length of composite web past a reference line during an advancing phase and for arresting the movement of the predetermined length during a dwell phase; the feed means com-prising at least one web advancing roller engaging a side of the web, a continuously rotating drive member, a link operatively coupled with the drive member for transforming the rotating mo-tion of the drive member into an oscillating motion for the link, and one way clutch means operatively coupling the link and the roller for rotating the roller through an angle of rotation during the advancing phase when the link oscillates in one direction and for arresting the rotation of the roller during the dwell phase when the link oscillates in the other direction; means defining a pivot axis for the link; adjustment means operatively coupled with the feed means for changing during normal operation of the feed means the predetermined length of composite web advanced by the feed means which includes crank arm means connected with the clutch means, bar means pivotally secured to the link and crank arm means, and means operatively connected with the link and the bar means for changing the distance between the pivot axis and the point at which the bar means is pivotally connected to the link to cause a corres-ponding change in the angle through which the roller is rotated; means for severing the predetermined length of composite web along the reference line during the dwell phase to form composite web segments; and means for stacking the segment so that the segments are secured to each other by the adhesive stripes.
Claim 3
Dependent Claim 55 words
Apparatus according to claim 1 wherein the means for pivotally securing the bar means to the link comprises a slider slideably carried by the link, and wherein the means for changing the distance comprises means for slideably moving the slider along the link and for maintaining the slider at a set position on the link.
