Abstract
Abstract Two parallel guide rails are arranged to put therebetween a stationary die of the hot-press machine and a table for sliding therealong respective movers by which a facing layer is carried from a first position to cover the table to a second position to cover the stationary die. First clamping means is disposed on the movers to clamp longitudinally opposed ends of the facing layer, and second clamping means is connected to the stationary die to clamp laterally opposed ends of the facing layer when the facing layer which has been kept clamped by the first clamping means is brought to the second position by means of the movers.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
257 words
A system for producing a trim board which comprises a substrate of corrugated paperboard and a facing layer which is laid on one side of said corrugated paperboard, comprising: a hot-press machine including a stationary die and a moveable die, said movable die being movable to press a facing layer against a shaped corrugated paperboard which is previously positioned on said stationary die; first means having a flat top surface which is located beside said stationary die and is substantially flush with the top of said stationary die; conveying means for conveying said facing layer from said flat top surface of the first means to said stationary die over said shaped corrugated paperboard, said conveying means including two spaced guide rails which extend in a substantially parallel relationship and which locate said stationary die and said first means therebetween, two movers which are slidable on and along said guide rails respectively between said first means and said stationary die, and a connecting rod having opposed ends respectively connected to said movers to provide simultaneous movements of said movers; first clamping means mounted to said movers and movable therewith, said first clamping means being capable of clamping longitudinally opposed ends of said facing layer on said flat top surface; and second clamping means mounted to said stationary die, said second clamping means being capable of clamping laterally opposed ends of said facing layer when said facing layer having been clamped by said first clamping means is brought, by said movers, to a position to cover said stationary die.
Claim 2
Independent Claim
257 words
A system for producing a trim board which comprises a substrate of corrugated paperboard and a facing layer which is laid on one side of said corrugated paperboard, comprising: a hot-press machine including a stationary die and a moveable die, said movable die being movable to press a facing layer against a shaped corrugated paperboard which is previously positioned on said stationary die; first means having a flat top surface which is located beside said stationary die and is substantially flush with the top of said stationary die; conveying means for conveying said facing layer from said flat top surface of the first means to said stationary die over said shaped corrugated paperboard, said conveying means including two spaced guide rails which extend in a substantially parallel relationship and which locate said stationary die and said first means therebetween, two movers which are slidable on and along said guide rails respectively between said first means and said stationary die, and a connecting rod having opposed ends respectively connected to said movers to provide simultaneous movements of said movers; first clamping means mounted to said movers and movable therewith, said first clamping means being capable of clamping longitudinally opposed ends of said facing layer on said flat top surface; and second clamping means mounted to said stationary die, said second clamping means being capable of clamping laterally opposed ends of said facing layer when said facing layer having been clamped by said first clamping means is brought, by said movers, to a position to cover said stationary die.
Claim 3
Dependent Claim
66 words
A system as claimed in claim 1, in which said first clamping means comprises: two spaced supports mounted on each of said movers; and two elongate plates each being swingably supported at longitudinally opposed ends thereof by the two supports, each of said elongate plates having a lateral edge which is brought into contact with the associated mover when said plate rotates in a predetermined direction.
Claim 4
Dependent Claim
20 words
A system as claimed in claim 2, in which said elongate plate is biased to rotate in said predetermined direction.
Claim 5
Dependent Claim
29 words
A system as claimed in claim 3, in which said first clamping means further comprises a handle which is connected to said elongate plate for manually operating the same.
Claim 6
Dependent Claim
30 words
A system as claimed in claim 3, in which said lateral edge of said elongate plate is bent inwardly to allow the plate to have a substantially L-shaped cross section.
Claim 7
Dependent Claim
94 words
A system as claimed in claim 3, in which said second clamping means comprises: brackets fixed to each of the opposed sides of said stationary die; two elongate plates, each plate being swingably supported on said brackets and having a lateral edge which is brought into contact with a flange member fixed to the associated lateral side of said stationary die when said plate rotates in a predetermined direction; and actuating means for actuating each of said elongate plates to rotate in said predetermined direction when said movers are moved to said stationary die.
Claim 8
Dependent Claim
35 words
A system as claimed in claim 6, in which said lateral edge of said elongate plate of said second clamping means is inwardly bent to allow the plate to have a substantially L-shaped cross section.
Claim 9
Dependent Claim
61 words
A system as claimed in claim 6, in which said actuating means comprises: a pinion gear coaxially fixed to said elongate plate of said second clamping means to be rotatable therewith; and a rack member meshingly engaged with said pinion gear, the longitudinal movement of said rack member inducing rotation of said pinion gear and thus rotation of said elongate plate.
Claim 10
Dependent Claim
59 words
A system as claimed in claim 1, in which each of said guide rails of said conveying means is a tubular member which has a longitudinally extending slit, and in which each of said movers comprises a cylindrical section slidably disposed in said tubular member, and a flange section extending from said cylindrical section and passing through said slit.
Claim 11
Dependent Claim
35 words
A system as claimed in claim 9, in which said longitudinal end section of said flat top surface is formed with a recess into which the leading end of said flange section is slidably received.
