Abstract

Abstract Apparatus for applying a surfacing sheet such as a plastic sheet, veneer or the like to an optionally radiused edge of a panel, or to a column or the like held by a support arrangement, and, in which an applicator bar which is, optionally heated and is preferably flat, is urged against the surfacing sheet to press it onto the surface of the panel column or the like. Means are provided for ensuring that lateral movement of the applicator bar takes place relative to the panel or column to stretch and smooth the surfacing sheet onto the surface of the panel or column. The applicator bar is preferably carried on an arm arrangement held between two spaced rotatable end supports and the biasing is carried out by a number of spaced pneumatic or hydraulic piston and cylinder assemblies acting transverse to the arm arrangement. The biasing means is preferably carried on a frame member carried by the rotatable end supports. The support arrangement is movable and may be either an adjustable table or rotatable to axial mounting assemblies for rotating a column or the like gripped end on between them. A jig may be included to space an edging strip relative to an edge of a panel if required.

Claims Analysis

Total Claims: 14

Claim 1

Independent Claim 116 words

Apparatus for applying sheet material around an edge or corner of a carrier member, said apparatus comprising a frame, a support arrangement for the carrier member for supporting it in a roughly predetermined position relative to the frame of the apparatus, an applicator bar associated with the frame and extending along the required length of the support arrangement, means for urging the applicator bar towards the surface of a carrier member supported in the apparatus, means for causing simultaneous lateral movement of the applicator bar relative to said surface whilst in contact therewith and lateral restraining means for inhibiting uncontrolled or undesired lateral movement of the applicator bar, the support arrangement being movable to the frame.

Claim 2

Dependent Claim 116 words

Claim 3

Dependent Claim 20 words

Apparatus as claimed in claim 1 in which the support arrangement is a movable table and clamping member co-operating therewith.

Claim 4

Dependent Claim 13 words

Apparatus as claimed in claim 2 in which the table is vertically movable.

Claim 5

Dependent Claim 27 words

Apparatus as claimed in claim 1 in which the support arrangement includes a pair of opposed, coaxial rotatable, mounting assemblies for mounting columns or the like therebetween.

Claim 6

Dependent Claim 27 words

Apparatus as claimed in claim 1 in which a jig is included for locating an edging strip relative to an edge of a panel or the like.

Claim 7

Dependent Claim 21 words

Apparatus as claimed in claim 1 in which the applicator bar embodies heating means for selectively heating the bar as required.

Claim 8

Dependent Claim 29 words

Apparatus as claimed in claim 1 in which the applicator bar and lateral restraining means associated therewith are carried on end supports rotatable in unison relative to the frame.

Claim 9

Dependent Claim 39 words

Apparatus as claimed in claim 7 in which there are at least two primary frame members extending between the two end supports, one of which carries the urging means and the other of which carries the lateral restraining means.

Claim 10

Dependent Claim 27 words

Apparatus as claimed in claim 1 in which the urging means comprises a series of individual biasing arrangements spaced apart along the length of the applicator bar.

Claim 11

Dependent Claim 24 words

Apparatus as claimed in claim 1 in which the urging means are composed of a plurality of pneumatic or hydraulic piston and cylinder assemblies.

Claim 12

Dependent Claim 27 words

Apparatus as claimed in claim 1 in which the lateral restraining means is an arm arrangement extending transverse to the direction of urging of the applicator bar.

Claim 13

Dependent Claim 19 words

Apparatus as claimed in claim 1 in which the applicator bar is hingedly mounted relative to said urging means.

Claim 14

Dependent Claim 14 words

Apparatus as claimed in claim 1 in which the applicator bar is substantially flat.
