Abstract

Abstract Apparatus for making a laminated panel with skins of sheet material adhesively secured to a core advances the core in vertical disposition and conveys the skins to and advances them adjacently with the core; and an adhesive applicator applies adhesive to one of each pair of skin and core surfaces to be adhered before the skins meet the core, the applicator including nozzles to direct fluid adhesive onto the upper part of said surface, a plurality of flexible fingers and means for reciprocating the fingers in sequence between the upper and lower parts of said surface.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 133 words
Apparatus for making a laminated panel with an inner core section and outer skins of sheet material adhesively secured to the substantially parallel side faces of the core including means for advancing the inner section in substantially vertical disposition; means for conveying the skins to and advancing them adjacently with the core; an adhesive applicator for applying adhesive to one of each pair of surfaces of skin and core to be adhesively secured together before the skins are brought adjacent to the core, such adhesive applicator consisting of means for directing fluid adhesive onto the upper part of said surface, a plurality of flexible fingers, and means for reciprocating the said fingers sequentially between the upper and lower parts of the said surface; and means for passing the two skins to the core.
Claim 2
Dependent Claim 133 words
Apparatus for making a laminated panel with an inner core section and outer skins of sheet material adhesively secured to the substantially parallel side faces of the core including means for advancing the inner section in substantially vertical disposition; means for conveying the skins to and advancing them adjacently with the core; an adhesive applicator for applying adhesive to one of each pair of surfaces of skin and core to be adhesively secured together before the skins are brought adjacent to the core, such adhesive applicator consisting of means for directing fluid adhesive onto the upper part of said surface, a plurality of flexible fingers, and means for reciprocating the said fingers sequentially between the upper and lower parts of the said surface; and means for passing the two skins to the core.
Claim 3
Dependent Claim 31 words
Apparatus according to claim 1 wherein the flexible fingers are mounted on and extend in substantially parallel arrangement from a sprocket-mounted endless chain means being provided for driving the said chain.
Claim 4
Dependent Claim 37 words
Apparatus according to claim 2 wherein the sprocket-mounted endless chain is mounted on a base member movable to operative position, the fingers contacting the said surface, or to inoperative position, the fingers clear of the said surface.
Claim 5
Dependent Claim 86 words
Apparatus according to claim 1 wherein the means for advancing the outer sections and interposed inner section, and for pressing the outer sections to the inner section, include a series of resilient substantially vertical pressure rollers, fixedly mounted on a main frame, and a series of corresponding resilient substantially vertical pressure rollers laterally adjustably mounted on the main frame, a drive for counter-rotating the said pressure rollers of the two series and means for moving the adjustable pressure rollers towards or from said fixed pressure rollers.
