14 Claims. (Cl. 271--2.6)

This invention relates to apparatus for guiding and spreading a moving web of material such as carpet, cloth or other like material and is particularly designed to guide a web of carpet while being fed to a piece dye machine.

In dyeing cotton carpet in open widths in a piece dye machine difiiculty is experienced in keeping the moving carpet from moving from side to side on what is known as the large reel of the dye machine. In moving from side to side, folds are formed in the carpet with the result the carpet enters the dye machine in a lapped over condition which is highly undesirable.

it is an object of the present invention to provide automatic means for guiding and spreading a web of material such as cotton carpet as it is being fed to a dye machine so that it enters the dye machine in full open width and free of any distortions.

A further object of the inven ion resides in providing apparatus of the above-mentioned character which is simple and durable in construction, reliable and efficient in operation and inexpensive to manufacture.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same.

Referring to the drawings, the numeral 5 designates a web of material such as cotton carpet which is being fed into a piece dye machine, not shown. The material 5 passes over a guide roll 6 having a shaft 7 extending from each end that is rotatably mounted in suitable bearings 3 forward of the large reel of the dye machine. The peripheral surface of the roll 6 is divided circumferentially into three sections one of which is provided with a series of raised ribs 9 spaced apart longitudinally of the roll which are inclined with respect to the direction of rotation in an upwardly and outwardly direction towards the right end of the roll. Another section of the surface has second series of raised ribs 10 inclined in the opposite direction towards the left end of the roller and the section between the two ribbed sections is smooth, as at 11. When the roll 6 is rotated to bring the ribbed section 9 in contact with the material 5, the material is moved towards the right side of the roll and When it is desired to move the material towards the left side, the roll is rotated to bring the ribbed section 10 in contact with the material. The smooth section 11 is brought into contact with the material when the material is moving in a straight course.

The mechanism for turning the roll 6 to bring the desired section of its surface in contact with the material consists of a pair of pneumatic cylinders 12 and 13 having reciprocating pistons with piston rods 14 and 15 ex tending from one end of the cylinders. The cylinders are disposed in parallel relation and the piston rod 14 of cylinder 12 is connected to one end of a roller chain 16 which is trained around a sprocket wheel 17 and has its opposite end connected to the piston rod 15 of cylinder 13. The sprocket wheel 17 is fixed on one end of the shaft 7 of roll 6 and adjacent the sprocket wheel is an arm 18 affixed to the shaft which is normally moved by spring 19 to rotate the roll to bring and hold the smooth section 11 in contact with the material. The spring 19 has one end attached to the arm 18 and its opposite end to a fixed point 20. The piston rods of the cylinders 12 and 13 are moved towards the lower end of the cylinders by coil springs 21 and 22 having one end aflixed to laterally extending pins 23 and 24 at the lower end of the cylinders and their opposite ends to pins 25 and 26 extending from the upper ends of piston rods 14 and 15. When the piston rods of both cylinders are in retracted position the smooth section 11 of roll 6 is in contact with the material and is held in this position .by the pull of spring 19 on arm 18, as shown in Fig. 5. Solenoid air valves 27 and 28 control the admission of compressed air to the cylinders through conduits 29 and 39 connected to the lower ends of the cylinders. The electric circuit 31 of the solenoid air valves having micro switches 32 and 33 interposed in the circuit for controlling the air valves 27 and 28, respectively. The switches 32 and 33 are disposed above the material on opposite sides thereof and pivotally suspended adjacent the switches are feeler arms 34 and 35 having their lower ends 36 and 37 disposed adjacent the opposite edges of the material for contact therewith if the material moves towards the right or left. When the material diverges from a straight course and moves to the left the feeler arm 34 will swing outwardly and close the micro switch 32 to actuate the solenoid air valve 27 to admit air to the cylinder 12 and thereby extend the piston rod 14 to move the chain 16 and thus rotate the roll to bring the ribbed surface 9 into contact with the material. Owing to the inclination of the ribs on the surface 9 the material will be moved towards the right of the roll and as it moves to the right the feeler arm 34 will move out-of contact with the switch 32, opening the circuit of the solenoid valve 27 to close the valve and allow the air in cylinder 12 to be exhausted through the exhaust port 38 of the valve. As the air exhausts from cylinder 12 spring 21 retracts piston rod 14 which moves chain 16 to rotate roll 6 and bring the smooth surface 11 in contact with the material in which position it is held by the tension of spring 19 on the arm 18. Likewise if the material moves to the right the feeler arm 35 closes switch 33 to open air valve 28, admitting air to cylinder 13 to extend the piston rod 15 to move chain 16 to rotate roll 6 to bring the ribbed surface 10 into contact with the material and thus cause the material to move to the left. Thus, it will be seen that any deviation of the moving material from a straight course will result in either of the feelers 34 or 35 being actuated to close the circuits to the solenoid valves 27 or 28 to admit air to the pneumatic cylinders 12 or 13 for operating the roll 6 to bring the ribbed surfaces 9 or 10 into contact with the material and thereby direct the material back to a straight course so it will be fed to the dye machine in full open width.

A modified form of guide roll is shown in Figs. 8 to 14, inclusive, and comprises a plurality of rolls 38, 39 and 40 fixedly mounted in arcuate brackets 41. The shaft 42 of the center roll 39 extends beyond the brackets and is rotatably mounted in suitable bearings 43 and as the brackets 41 are fixed on shaft 42 rotation of the shaft will swing the brackets to bring the rolls 38, 39 and 40 selectively into contact with the material 44 being fed to the dye machine. The roll 38 has a spiral rib 45 formed thereon which may be formed by spirally winding a piece of wire around the roll with the spirals extending in a direction towards the right hand end of the roll. When this roll contacts the material the material is guided towards the right. The roll 40 is likewise provided with a spiral rib 46 with the spirals extending in a direction towards the left hand end of the roll and when this roll is in. contact with the material the material is guided towards the left. The center roll 39 is provided with a spiral rib 47 with the spirals extending from the center of the roll in opposite directions and when this roll is in contact with the material, the material is guided in a straight course.

The mechanism for selectively bringing the rolls in contact with the material is the same as the mechanism employed in the form of the invention shown in Fig. 1. It comprises pneumatic cylinders 48 and 49 having piston rods 50 and 51 connected to the ends of a roller chain 52 that is trained over a sprocket wheel 53 fixedly mounted on shaft 42. The piston rods are normally retracted by springs 54 and 55 connected at one end to pins 56 and 57 extending from the bottom of the cylinders and at their opposite ends to pins 58 and 59 extending from the piston rods. Air for operating the piston rods is admitted to the cylinders by solenoid valves 60 and 61 connected by conduits 62 and 63 with the cylinders. The solenoid valves are controlled by an electric circuit 64 having micro switches 65 and 66 interposed in the circuit which are actuated by the pivotally suspended feeler arms 67 and 68 having their lower ends disposed on opposite sides of the material so as to be engaged by the edge of the material if it moves to the right or left. Air admitted to cylinder 48 will rotate shaft 42 to bring roll 38 into contact with the material and air admitted to cylinder 49 will reverse the rotation of shaft 42rto bring the roll 40 into contact with the material. When the air valves 69 and 61 are closed, the springs 54 and 55 retract the piston rods and rotate shaft 42 to bring the roll 39 into contact with the material in which position it is held by the tension of spring 69 on the arm 70 affixed to shaft 42.

From theforegoing it is apparent the mechanism provided will spread and guide the moving web of material in a straight course and will prevent any deviation of the material to the right or left so that it will be fed to the dye machine in full open width and which is completely automatic in operation. 7 7
