A fabric roll is produced by winding a fabric (4) around at least two reels, that are coaxially aligned, spaced from each other, and have a total length (L) that is less than the width (Wr) of said fabric roll (11).

A core member is provided for storing shrink film. The core member includes a plurality of rollers, each having a disc and a core extending upwardly from the disc. The plurality of rollers are aligned longitudinally along an axis and laterally along a plane. The plurality of rollers are rotatable to wind the shrink film about the rollers.

A roll holder is inserted with a hollow tube of one of a first roll having a first inner diameter and a second roll having a second inner diameter greater than the first inner diameter. The roll holder includes a holder and a cam assembly that are supported by a support shaft and movable in an axial direction of the support shaft. The cam assembly includes an abutment and a cam. The abutment contacts a lateral end of the second roll in the axial direction of the support shaft. The cam presses against one of a first presser and a second presser of the holder in a radial direction of the support shaft to cause the one of the first presser and the second presser to press against and hold an inner circumferential face of the hollow tube of the one of the first roll and the second roll.

A pipe lining apparatus having a pressure sensitive adhesive backed reinforcement filament that is helically wound onto the inner surface of a pipe or pipe lining by an inverted filament winding apparatus, the apparatus having multiple spools and applicator arms to retain and apply the filament. The applicator arms may be aligned circumferentially or axially.

A spool endform assembly includes an endform with a central collar that are configured to rotate about a rotational axis. The spool endform assembly further includes a mount sub-assembly configured to be mounted in a fixed orientation on a mounting structure (such as movable arm). The spool endform assembly is further configured to permit misalignment of the fixed orientation of the mount sub-assembly relative to the rotational axis of the endform and central collar. In embodiments, controlled movement of the mounting structure can be used to connect the spool endform assembly to a rotatable mandrel of a wire winding spool and disconnect the spool endform assembly from the rotatable mandrel. By permitting misalignment of the fixed orientation of the mount sub-assembly relative to the rotational axis of the endform and central collar, the spool endform assembly makes it easier to connect the spool endform assembly to the rotatable mandrel and to disconnect the spool endform assembly from the rotatable mandrel. Other features and aspects are described and/or claimed.

A reel holder is disclosed. In some embodiments, the reel holder comprises an opening configured to receive and hold a reel having packaging material and a transceiver configured to communicate with a tag in the reel to receive information stored in the tag. A filling machine system is also disclosed. In some embodiments, the filling machine system comprises a reel holder and a reel provided with a tag.

Determining a remaining amount of material in a material package may be provided. First, a weight of the material package may be received in response to the ingress of the material package back into an operations area. Then, based upon a beacon code received in response to the ingress of the material package back into the operations area, a material database may be queried for a material package record. Next, a remaining amount of material corresponding to the material package may be calculated based upon the received weight and data from the material package record found from the material database query. The material package record may then be updated in the material database with the calculated remaining amount of material corresponding to the material package.
