Abstract

A manufacturing system (1) for manufacturing shaped laminates including: forming tools (2.1, 2.2) extending along a longitudinal direction X, located parallel to one another and configured to receive a laminate (4) between the forming tools; a shaping tool (3) extending along the longitudinal direction X and along a transversal direction Z, and configured to receive the laminate (4) on an external surface of the shaping tool, wherein the forming tools (2.1, 2.2) or the shaping tool (3) are movable in the longitudinal direction X and in the transversal direction Z, relative to the at least one of the shaping tool (3) and the two forming tools (2.1, 2.2).

Claims10

Dependent claims

A manufacturing method for manufacturing shaped laminates, the method comprising:

a) positioning a flat laminate sheet between forming tools, such that the flat laminate sheet is sandwiched between the forming tools,
b) compressing the flat laminate sheet between the forming tools by applying pressure to at least one of the forming tools,
c) discharging, after the step (b), a first portion of the flat laminate sheet from ends of the forming tools adjacent a shaping tool using a conveyor in the forming tools to move the laminate sheet;
d) in conjunction with the step (c), applying the first portion of the flat laminate sheet from the forming tools directly onto a first portion of an external surface of the shaping tool,
e) after the step (d), moving at least one of the forming tools and the shaping tool to position the ends of the forming tools to be proximate a second portion of the external surface of the shaping tool;
f) simultaneously with the step e), a plurality of fingers move with at least one of the forming tools to apply pressure to the laminate sheet on the external surface, and at least one of the fingers is nearer the external surface of the shaping tool than another of the fingers;
g) after at least the steps (c) and (d), discharging a second portion of the laminate sheet using the conveyor and applying the second portion directly from the forming tools to the second portion of the external surface, wherein the second portion is a continuation of the first portion of the laminate sheet;
and
h) shaping the laminate sheet to conform to the external surface by the steps (d) to (f).

6 more elements

A method comprising:

sandwiching a laminate sheet between forming tools;
compressing the laminate sheet between the forming tools, wherein the laminate sheet is flat when compressed between the forming tools;
discharging a first portion of the laminate sheet from ends of the forming tools, wherein the forming tools include a conveyor and the discharging of the first portion includes the conveyor moving the laminate sheet to discharge the first portion from the ends of the forming tools;
applying the first portion of the laminate sheet directly from the forming tools onto a first area of an external surface of a shaping tool while retaining a second portion of the laminate sheet between the forming tools;
moving at least one of the forming tools and the shaping tool to position the ends of the forming tools proximate a second area of the external surface of the shaping tool, wherein the second area is continuous with the first area;
after the moving step, discharging the second portion of the laminate sheet using the conveyor from the forming tools direction onto the second area, and
shaping the first and second portions of the laminate sheet to conform to the first and second areas of the external surface of the shaping tool,
wherein the step of shaping includes:
arranging fingers adjacent at least one of the forming tools wherein each of the fingers has a distal end proximate the external surface of the shaping tool,
pressing by the distal ends of the fingers the first portion of the laminate sheet on the first area of the external surface of the shaping tool, and
pressing by the distal ends of the fingers the second portion of the laminate sheet on the second area of the external surface of the shaping tool.

8 more elements

A method comprising:

sandwiching a first edge region of a laminate sheet between a first pair of forming tools and compressing the first edge region of the laminate sheet between the first pair of the forming tools;
sandwiching a second edge region of the laminate between a second pair of forming tools and compressing the second edge region of the laminate sheet between the second pair of forming tools;
applying the laminate sheet on an external surface of a shaping tool while the first edge region is compressed between the first pair of the forming tools and the second edge region is compressed between the second pair of the forming tools, wherein the first and second pair of forming tools are on opposite sides of the shaping tool;
discharging a first portion of the first edge region from ends of the first pair of the forming tools and onto the external surface of the shaping tool, wherein the first pair of forming tools include a first conveyor and the discharging includes the first conveyor moving the first edge region to discharge the first portion from the ends of the first pair of forming tools;
discharging a first portion of the second edge region from ends of the second pair of forming tools and onto the external surface of the shaping tool, wherein the second pair of forming tools include a second conveyor and the discharging of the first portion of the second edge region includes the second conveyor moving the second edge region to discharge the second portion from the ends of the second pair of forming tools;
moving the first and second pairs of forming tools and/or the shaping tool to move the first and second pairs of the forming tools relative to the external surface of the shaping tool,
after the moving, discharging a second portion of the first edge region from ends of the first pair of the forming tools and onto the external surface of the shaping tool, wherein the discharging of the second portion includes the first conveyor moving the second edge region to discharge the first portion from the ends of the first pair of forming tools;
after the moving, discharging a second portion of the second edge region from the ends of the second pair of forming tools and onto the external surface of the shaping tool, wherein the second pair of forming tools include a second conveyor and the discharging of the second portion includes the second conveyor moving the second edge region to discharge the second portion from the ends of the second pair of forming tools.
