Benefits of technology
[0020] Yet another object of the present invention is to increase efficiency and profitability by increasing the width, and therefore the overall quantity of grass continuously produced by a single machine, without sacrificing the accuracy of packaged material.
[0021] Still another object of the current invention is to more accurately package decorative grass by apportioning the grass into discrete aggregates in order to better manage the quantity of grass per charge.
Problems solved by technology
Weder '813 does not provide for dividing the uniform charges of decorative grass into discrete aggregates of decorative grass for packaging.

Embodiment Construction
[0036] Referring to the drawings in general, and to FIG. 1 in particular, shown therein and designated by the general reference numeral 10 is an apparatus for making and bagging decorative grass, which includes an extruder 12, a godet 14, a thickness gauge 16, a slitter 18, a cutter 20, a divider 21, a plurality of bagging assemblies 22 and a programmable logic controller (PLC) 24.
[0037] The extruder 12 is any conventional machine which produces a continuous sheet of flexible material from resins, colorants, additives, anti-static agents and flame retardants. A suitable extruder is disclosed in U.S. Pat. No. 4,292,266 issued Sep. 29, 1981 to Weder et al., which is hereby incorporated by reference.
[0038] Similarly, the godet 14 may be any known device for feeding sheet material from one location to another. A typical godet includes a plurality of rollers which are rotatable to dispense a continuous web of sheet of flexible material 26. In the present invention, the godet 14 receive...

Abstract
An apparatus and method for producing and bagging decorative grass, comprising an extruder, a godet, a slitter, a cutter, a divider, a bagging assembly and a programmable logic controller. The extruder produces a sheet of flexible material, which is fed by the godet into the slitter, cutter and divider. The slitter slits the sheet into a web of strands of material. The cutter cuts the web of strands, producing a quantity of decorative grass, which is then divided into discrete aggregates and sent by ducts to bagging assemblies, each of which has a rotatable turret having magazines for receiving and discharging discrete aggregates, an inserter and a bag handler. A programmable logic controller coordinates the production and bagging of the decorative grass, based on the properties of the sheet and the divider, and the predetermined properties of the decorative grass.
