Abstract

A device for performing the continuous cutting of materials of any form and nature, provided they are stratified and not flexionally rigid. The device generally comprises: fixed and mobile support surfaces; a mobile cutting shear cooperating with a fixed cutting shear; a fixed blocking unit on the fixed support surface side of the cutting shears; a mobile blocking unit on the mobile support surface side of the cutting shears; an eccentric for driving mobile portions of the device, including the mobile cutting shear, the eccentric being synchronized with the fixed and mobile blocking units; and a link block and slide guide. Non-rigid, stratified materials thereby may be more easily cut in that the invention substantially reduces or eliminates the dragging effect of the material that typically occurs during the cutting process.

Dependent claims

A method for simultaneously blocking and cutting at least one layer of non-rigid material having at least a first side and a second side, comprising the steps of:

placing a first side of said non-rigid material to be cut on a fixed support surface and a mobile support surface;
engaging a first portion of said second side of said non-rigid material with a fixed blocking unit to compress said non-rigid material on said fixed support surface whereby said non-rigid material is substantially secured in place on said fixed support surface;
engaging a second portion of said second side of said non-rigid material with a mobile blocking unit to compress said non-rigid material on said mobile support surface whereby said non-rigid material is substantially secured in place on said mobile support surface;
and
moving simultaneously a mobile wall, a mobile shear connected to said mobile wall a link block, said mobile support surface and a mobile support structure connected intermediate said mobile wall and said link block, in a substantially uniform direction such that said mobile shear cooperates with a fixed shear connected to said fixed support surface to cut said non-rigid material between said first and second portions of said non-rigid material, said mobile blocking unit being connected to a housed within said mobile support structure:
and
guiding movement of said mobile wall said mobile shear said mobile support surface, and said mobile support structure in said substantially uniform direction through cooperation of said link block with a slide guide.
