LAMINATING APPARATUS

摘要

The invention provides an apparatus and a process for producing laminated materials. The process comprises the steps of: (a) supplying material from a first supply roller; (b) supplying materials from a system (5) comprising a plurality of further supply rollers (7); (c) tracking lateral movement of the material leaving said first supply roller; and (d) adjusting the lateral position of said system (5) in response to said lateral movement, such that the lateral alignment of the plurality of further supply rollers remains constant with respect to the material leaving the first supply roller. The adjustment step (d) may be manual, or it may be automatic e.g. in response to tracking in step (c) by means of an electronic sensor (4) which tracks a control line (X) on the material leaving the first supply roller. By maintaining constant lateral alignment, it is possible to manufacture laminated materials comprising a layer made from strips of material which abut but which do not overlap.
