Abstract
Abstract Novel flocked products, their preparation and apparatus for use in their preparation are described. The products comprise a substrate with a surface of flocked fibres bonded to it by a hardened binder and the fibres over part of the surface have a predominant, non-perpendicular orientation and are substantially linear and over another part of the surface have a different, predominant, non-perpendicular orientation and are substantially linear. The products enable excellent design interest and resistance to use defects e.g. bruising to be readily achieved.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
118 words
A METHOD OF MAKING A FLOCKED PRODUCT COMPRISING A SUBSTRATE HAVING BONDED TO ITS SURFACE A LAYER OF FLOCKED FIBRES WHICH ARE SUBSTANTIALLY LINEAR AND WHICH, IN DIFFERENT PARTS OF THE SURFACE, HAVE DIFFERENT PREDOMINAT NON-PERPENDICULAR ORIENTATIONS, SAID METHOD COMPRISING THE STEPS OF: A. APPLYING FLUID BINDER TO THE SURFACE OF THE SUBSTRATE, B. FLOCKING FIBERS ONTO THE FLUID BINDER, C. LAYING THE FLOCKED FIBRES IN A FIRST PART OF THE AREA OF THE SURFACE IN A PREDOMINANT NON-PREPENDICULAR DIRECTION WHILE MAINTANING THEM SUBSTATIALLY LINEAR BY ROLLING A STENCIL HAVING PERFORATIONS IN THE PERIPHERA SURFACE THEREOF OVER AND IN CONTACT WITH THE PRODUCT WITH NO RELATIVE MOVEMENT AT THE ZONE OF CONTACT BETWEEN THE STENCIL AND THE PRODUCT,

Claim 3
Dependent Claim
62 words
A method according to claim 1 in which the separately movable orienting means comprise a rotatable brush whose axis is parallel with the axis of the stencil and whose bristles extend to but not beyond the perforations where they are in contact with the product and which rotates at a speed faster than the stencil in the same direction as the stencil.
Claim 4
Dependent Claim
15 words
A method according to claim 1 in which the fibres are precision cut flock fibres.
Claim 5
Dependent Claim
17 words
A method according to claim 1 in which the fibres are less than 1.5 mm. in length.
Claim 6
Dependent Claim
45 words
A method according to claim 1 in which the fibres in the first part of the surface area and the fibres in the second part of the surface area lie substantially all at an angle of less than 45* to the plane of the surface.
Claim 7
Independent Claim
238 words
A method of making a flocked product comprising a substrate having bonded to its surface a layer of flocked fibres which are substantially linear and which, in different parts of the surface, have different predominant non-perpendicular orientations, said method comprising the steps of: a. applying fluid binder to the substrate; b. electrostatically flocking precision cut flock fibres less than 1.5 mm. in length onto the fluid binder; c. laying the fibres in a first part of the surface area in a predominantly non-perpendicular orientation which is at an angle of less than 45* to the plane of the surface while maintaining them substantially linear by rolling a stencil over and in contact with the product with no relative movement at the zone of contact between the stencil and the product; d. laying the fibres in a second part of the surface area of the product in a different predominant orientation which is opposite to and substantially parallel to the first orientation and which is such that the fibres are substantially all at an angle of less than 45* to the surface, while maintaining them substantially linear, by rotating in the same direction as, but faster than, the stencil a rotatable brush which is mounted in the stencil with its axis parallel with the stencil and whose bristles extend to but not substantially beyond the perforations where they are in contact with the product; and e. hardening the binder.
Claim 8
Independent Claim
238 words
A method of making a flocked product comprising a substrate having bonded to its surface a layer of flocked fibres which are substantially linear and which, in different parts of the surface, have different predominant non-perpendicular orientations, said method comprising the steps of: a. applying fluid binder to the substrate; b. electrostatically flocking precision cut flock fibres less than 1.5 mm. in length onto the fluid binder; c. laying the fibres in a first part of the surface area in a predominantly non-perpendicular orientation which is at an angle of less than 45* to the plane of the surface while maintaining them substantially linear by rolling a stencil over and in contact with the product with no relative movement at the zone of contact between the stencil and the product; d. laying the fibres in a second part of the surface area of the product in a different predominant orientation which is opposite to and substantially parallel to the first orientation and which is such that the fibres are substantially all at an angle of less than 45* to the surface, while maintaining them substantially linear, by rotating in the same direction as, but faster than, the stencil a rotatable brush which is mounted in the stencil with its axis parallel with the stencil and whose bristles extend to but not substantially beyond the perforations where they are in contact with the product; and e. hardening the binder.
Claim 9
Dependent Claim
46 words
Apparatus comprising a support for sheet material, a stencil having openings in the surface thereof rotatable in contact with sheet material carried on the support, and separately movable orienting means contained in the stencil for orienting fibres at the openings in the surface of the stencil.
Claim 10
Dependent Claim
46 words
Apparatus comprising a support for sheet material, a stencil having openings in the surface thereof rotatable in contact with sheet material carried on the support, and separately movable orienting means contained in the stencil for orienting fibres at the openings in the surface of the stencil.
Claim 11
Dependent Claim
65 words
Apparatus according to claim 7 in which the separately movable orienting means comprise a rotatable brush whose axis is parallel with the stencil, whose bristles extend to but not substantially beyond the perforations in the stencil surface where they may contact the sheet material on the support, and which is rotatable at a speed faster than the stencil in the same direction as the stencil.
Claim 12
Dependent Claim
46 words
Apparatus according to claim 7 additionally comprising means for applying a fluid binder to the sheet material, means for flocking fibres onto the fluid binder before the sheet material contacts the stencil, and means for hardening the binder after the sheet material has contacted the stencil.
