An apparatus to roll-up a lane of compressible material includes a first endless conveyor belt, a second endless conveyor belt that forms an angle of between 50.degree. and 80.degree. with the first belt, a winding roller that, with the first and second belts, form a winding space, and a third endless conveyor belt between the first and second belt. The third belt includes a guide plate above the upper portion and the lower portion runs in the same direction and at the same speed as the first belt.

Apparatus is provided for packaging compressible material, such as building insulation, in strip form. The compressible strip is wound into a roll and held under compression during rolling to form a compact package. The apparatus includes a main endless belt carried on a frame and positioned and driven in a manner to form a loop in itself which is in the path of the compressible strip being lineally moved toward the belt. The belt is driven to roll the strip on itself as it is moved into the loop, and means are provided for maintaining the belt under tension to place the strip in compression during rolling. When the roll is completed, part of a sub-frame for the belt is moved away from a main frame to cause the loop to open and automatically eject the compressed, packaged roll. A plurality of supporting belts is positioned under a portion of the loop and serves to aid in supporting the loop and the roll as it is being formed and also to provide the drive for the main belt. The supporting belts are driven so that the portions in contact with the main belt loop are in tension and preferably are timing belts. The belts are also at a steeper angle to the horizontal than heretofore.

A mat rolling machine for rolling a mat having a leading edge and a trailing edge may include a frame, at least one first drive belt, a plurality of second drive belts, a plurality of third drive belts, and a plurality of fourth drive belts. At least one of the belts may be coupled together at an oblique angle relative to the direction of travel of the belt. The mat rolling machine may include a plurality of primary fingers and a plurality of secondary fingers having a smaller radius of curvature on a lower face than the plurality of primary fingers. The mat rolling machine may include at least one support member for guiding a mat along a path through the mat rolling machine, and at least one pusher for discharging a rolled mat from the rear of the mat rolling machine.

Apparatus is provided for packaging compressible material in strip form, such as building insulation. The compressible strip is wound into a roll and held under compression during rolling to provide a compact package. The compressed package can then be held by two tapes, without additional overwrap, which tapes are automatically fed onto an end portion of the compressible strip as it is being rolled up, with the package then being automatically ejected. The apparatus includes an endless belt carried on a frame and positioned and driven in a manner to form a loop in itself which is in the path of the compressible strip being lineally moved toward the belt. The belt is driven to roll the strip as it is moved into the loop and means are provided for maintaining the belt under tension to place the strip in compression. The tension means for the belt also can increase pressure on the strip during rolling, and as the loop and roll enlarge, although the tension means can be arranged to reduce the pressure, if desired. The tape is fed from underneath to a trailing end portion of the strip and is wrapped around the roll after entering the loop. When the roll is completed, part of the frame for the belt is moved away from a stationary part to open the loop and automatically eject the compressed, packaged roll. The apparatus includes a multi-zone, suction conveyor to aid in feeding the compressible strip into the loop. The apparatus also includes facilities for relatively easily removing and replacing the endless belt, when needed.

A packaging machine (10) includes a machine foundation (22) and a variable-width belt system (24). The variable-width belt system (24) is moved relative to the packaging machine and configured to establish a belt pocket (26). A product is admitted into the belt pocket and rolled onto itself to establish a rolled product (16) as the belt moves relative to the machine foundation (22).

A method and apparatus for forming spiral wound rolls from strips of compressible material uses a first endless belt conveyor to deliver the strips of compressible material into a winding space. As the strip enters the winding space, the strip is compressed by a compression and slider plate to the desired thickness for the layers of strip material in the spiral roll. Then, the leading portion of the strip successively contacts: an inclined, second endless belt conveyor, a compression roll, and a third endless belt conveyor which together with the first conveyor define the winding space. The second conveyor extends upwardly at an acute angle to the first conveyor and as the strip of compressible material contacts the second conveyor it maintains the strip in compression and starts to turn the strip back upon itself to form the spiral roll. The strip next contacts the compression roll which is located intermediate the first and second conveyors. The compression roll continues to turn the strip back upon itself and maintains the strip in compression. The strip next contacts the third conveyor which is located intermediate to the compression roll and the first conveyor. The third conveyor maintains the strip in compression and guides leading portions of the strip inside trailing portions of the strip being fed into the winding space by the first conveyor to complete the spiral winding of each layer of the strip in the roll. The compression roll and the third conveyor and compression and slider plate are moved to enlarge the winding space as the diameter of the spiral roll increases during the winding operation.

Apparatus for forming a cylindrical element from a fibrous web, the element having a predetermined density characteristic radially thereof, comprises an endless belt, guide means about which said belt is entrained and which are arranged to define a loop in said belt to which loop the fibrous web is fed, said guide means being arranged so that, in use, said loop extends around substantially the entire circumference of the element forming in said loop, means for driving said belt so as to thereby cause the fibrous web to be fed into said loop and there to roll up on itself, and means for progressively increasing the diameter of said loop, said loop diameter increasing means including a control member about which said belt is entrained and which is movable to vary the dimensions of said loop, and means for moving said control member so as to increase the diameter of said loop at a rate which is a function of the linear speed of the belt and the length and weight per unit length of the fibrous web so as to obtain the predetermined radial density characteristic of the cylindrical element to be formed in said loop.
