Definitions
- the present invention relates to an apparatus for cutting paper or similar sheets of material and a method of producing such an apparatus.
- Paper cutting apparatus are well know for example guillotines and paper slicers with rotatable blades which cut along a fixed edge.
- guillotines and paper slicers with rotatable blades which cut along a fixed edge.
- the present invention seeks to provide another paper cutting apparatus.
- a cutting apparatus for cutting paper comprising cutting means having a cutting line along which blade means are arranged to cut, and further including a support surface extending from the cutting means to a distal edge, wherein the support surface is pivotably mounted so that the distal edge is pivotable towards the cutting means.
- the blade means is manually movable.
- the blade means includes a rotatable blade, the cutting edge of which is movable along the cutting line. This allows a particularly simple and compact apparatus.
- the rotatable blade may be movable along a support beam and in which case the support beam may be connected to a back member which back member is a structural member of the a cutting apparatus.
- the cutting line will normally comprise the edge of a fixed blade on a base member.
- the base member is advantageously a structural member of the a cutting apparatus and the support surface comprises a front member which is also advantageously a structural member.
- the structural members comprise a housing which essentially enclose the cutting means when the distal edge of the support surface has been pivoted towards the cutting means.
- some or each of the structural components comprises an extruded component.
- the extruded component may be an extruded aluminium component.
- The, some or each structural component of the cutting apparatus is advantageously shaped to resist a bending moment along the cutting line.
- the components may be curved to resist bending in a particular direction.
- the support surface preferably includes guide means for guiding the paper to the cutting means.
- a method of producing a cutting apparatus including the steps of providing:
- the cutting apparatus includes structural members where the, some or each structural member is an extruded member, such as an extruded aluminium member.
- an extruded member such as an extruded aluminium member.
- the cutting apparatus of the present invention is formed from a number of component parts. These may be assembled in to the apparatus of Figs. 1 and 2.
- the apparatus has structural components which form a housing about the cutting components .
- the main structural components are base member 5, the front member 4 and back member 3. These three member 3, 4 and 5 are connected together by means of a pair of opposed side plates 39, 40. Each end plate 39, 40 is attached to each structural components by screws 23.
- a fixed cutting blade 12 is formed from mild steel and fixed to base member 5 by screws 21 underneath pressure rail 35.
- Two runners 47 form support feet for the apparatus and are inserted into channels in base member 5.
- a cutter housing 32 houses a rotary cutter 13 made from stainless steel.
- the rotary cutter is fitted into the cutter housing 32 on a shaft 14.
- a splined cutter locator 37 holds one side the rotary cutter in position against a pressure wheel 45.
- the other side of the rotary cutter 13 is held in position by a spring 16 acting through washer 19 against a pressure plate 36 which abuts the rotary cutter 36.
- the cutter housing 32 is slidably mounted in a channel on back member 3.
- the cutter housing is manually movable in the channel.
- the rotary cutter 13 rotates as the housing is slid along the channel.
- the interface between the rotary cutter 13 and the fixed cutter 12 defines a cutting line.
- the front member 4 is mounted on to the side covers 39, 40 via a pair of pair guides 29, 30.
- the front member is mounted to be movable between a first position ('cutting' as shown in Fig. 1) and a second position ('closed' as shown in Fig. 2) by rotation about an axis substantially parallel to the cutting line.
- Extrusions 42 on each paper guide 29, 30 fit in to corresponding recesses 41 in the respective side members 39, 40.
- the recesses 41 are shaped as a blind channel to allow the extrusion 42 to be moved between the two positions.
- the paper guide 39 includes a high level paper guide 43. Whereas the paper guide 30 includes a low level paper guide 44.
- the pivotable nature of the front member 4 allows for the apparatus to be a particular compact design as it eliminates the large paper support surface when the apparatus is not in use.
- the physical dimensions of the apparatus are relatively small compared to previously known cutters having equivalent blade length.
- the cutting apparatus is made to be portable, i.e. transportable in a briefcase.
- the relatively small size is attributable to the structural members 3, 4, 5 and the side panels 39, 40 being curved to resist a bending moment on the cutter housing support towards the fixed cutter 12.
- the generally triangular cross-sectional shape of the housing also provides additional strength to the apparatus.
- the structural member(s) 3, 4, 5 are extruded, preferably from aluminium or other suitable material such as a plastics material of suitable torsional strength. This allows for the blade length the be altered without requiring different plant and tooling for different blade lengths.
- references to paper or the cutting thereof refers to any sheet material, such as plastics sheet used with overhead projectors.
- Figure 3 shows an exploded view of the apparatus according to a preferred embodiment of the invention.
- Figure 3 shows the following components: spring (16); washer (19); pressure plate (36); rotary cutter (13); shaft (14) ; cutter locator (37); pressure wheel (45); cutter housing (32); fixed cutter (12); base extrusion (5); left side end cap (39); first screws (23); left side paper guide (29); back extrusion (3); pressure rail (35); second screws (21); right side end cap (40); right side paper guide (30); from extrusion (4), and 2 x feet (47).
- the present invention relates to an apparatus for cutting paper or similar sheets of material and a method of producing such an apparatus.
- the cutting apparatus includes a cutting means having a cutting line along which blade means are arranged to cut.
- a support surface extends from the cutting means to a distal edge and the support surface is pivotably mounted so that the distal edge is pivotable towards the cutting means.
