Abstract
A web formed of a multiplicity of general parallel fibers or filaments is fed downwardly and incrementally toward a platen forming a lower element of a generally horizontal guide. A shear periodically moves across the path of the web so as to shear from the end thereof a section having a length slightly greater than the height of the guide. The lower edge of the upper element of the guide constitutes one of the shear elements so that as each section is cut off it is pressed into the end of the guide. Simultaneously with each cutting operation the stack formed in the guide is moved incrementally toward the downstream end thereof. As the stack emerges from the downstream end the sections are pressed end-wise into an adhesive layer on a substrate.
Claims2
An apparatus for making a nonwoven plush-type cloth, said apparatus comprising:
- a generally horizontal guide having a horizontal upper guide element and a lower guide element spaced vertically apart by a predetermined distance, said guide having an upstream end and a downstream end,
- feed means for advancing a web downwardly toward said upstream end,
- cutting means at said upstream end for severing from said web sections having a length slightly greater than said distance and for pushing the cut sections into said upstream end of said guide to form therein a stack, whereby said stack is displaced horizontally toward said downstream end by an increment each time a new cut section is pushed into said upstream end;
- and
- compression means at said downstream end for pressing said sections as they emerge therefrom endwise down into an adhesive coated substrate, said cutting means including a blade horizontally displaceable across said upper guide element and forming therewith a shear, said feed means advancing said web downwardly in increments equal to said length said guide being spaced above and parallel to said substrate at said upstream end and said downstream end being turned downwardly toward said substrate, means for coating said substrate with an adhesive and means for advancing said substrate so coated past said downstream end of said guide, said compression means at said downstream end including a horizontal support for said substrate and a band spaced above said support and driven at substantially the same speed as the advance speed of said substrate.
A method of making a plush-type cloth, said method comprising the steps of:
- a. advancing a substrate along a horizontal path;
- b. applying an adhesive layer to the upper surface of said substrate;
- c. advancing a web of plush-forming material downwardly toward said layer in a vertical direction;
- d. intercepting the leading lower edge of said web above said adhesive layer on a horizontal guide prior to engagement of said web with said surface;
- e. severing a section from said web by displacing a blade horizontally above said guide and against an upper horizontal guide forming a counterblade, said guides defining a horizontal channel spaced above but parallel to said substrate;
- f. pressing the cut section into said channel, thereby forming a succession of cut sections in the form of a horizontal stack within said channel;
- g. deflecting said stack downwardly toward said adhesive layer with said sections substantially perpendicular to said substrate;
- h. pressing said sections applied to said adhesive layer into the latter to implant the respective lower edges of said sections therein by passing said sections between a belt spaced above and parallel to said substrate;
- and
- i. setting said adhesive layer.
