    Abstract: A method for producing a convolute paper core of a desired width and thickness, the method including unwinding paper from a paper roll, thereby creating unwound paper, conveying the unwound paper to a cutting position in a feeding direction, cutting the unwound paper, thereby creating a paper sheet having a length L, conveying the paper sheet from the cutting position to a mandrel in a winding direction, wherein the winding direction is perpendicular to the feeding direction, adhesively and convolutely winding the paper sheet on the mandrel so as to produce a paper core, so that a width W of the paper core is equal to the length L, and repeating the steps of unwinding, conveying, cutting, conveying and adhesively and convolutely winding a plurality of paper sheets until the paper core has the desired thickness.

    Abstract: The tubular core (1) for tissue paper rolls consists of at least one tape (10) of tissue paper with one or more spirally wound tapes, such that the pitch of the winding helix is much smaller than the width of the tape (10) itself, so that two consecutive coils (S) are partially overlapped. In the tubular core (1) there may be several tissue paper tapes (10) wound simultaneously in relative helical coils preferably offset along the longitudinal axis of the same tubular core (1). The coils (S) of each tape (10), in the areas in which they are partially overlapped, are mutually fixed by means of an adhesive film (2) interposed between them. The adhesive film (2) is preferably continuous according to the winding direction of the coils (S) themselves. The presence of said adhesive films (2) produces a solid connection between the helical coils (S) and confers the necessary structural resistance to the tubular core (1) to receive, for wrapping on it, a tissue paper roll for hygienic use or domestic or other tape material.

    Abstract: A spool or reel for carrying spoolable or coilable material comprises first and second sides, a drum disposed there between at least one flange secured to a side and associated with the axis of rotation of the spool. The flange comprises a socket preferably centered about the axis of rotation and configured to receive a replaceable wear hub. The flange and replaceable wear hub are configured to transmit torque there between so that relative rotation between the components is minimized or eliminated.

    Abstract: A device comprises two identical side structures (or halves) attached to each other. The side structures are separable for packaging and storage. Each side structure comprises an outer ring attached to a concentric, elevated inner ring by at least one spanning support. The inner ring comprises a handle attached to the inner perimeter of the inner ring. Each side structure comprises at least one projecting attachment tang and at least one receiving notch. The attachment tang further comprises a head element and a body element. The body element extends axially from the inner ring and the head element extends radially from the body element. The attachment tang and receiving notch are located on the inner ring such that when two side structures are brought together, the attachment tang on one side structure mates with, and is received by, the corresponding receiving notch on the second side structure.

    Abstract translation: 一种装置包括彼此附接的两个相同的侧面结构（或半部）。 侧面结构可分开包装和储存。 每个侧面结构包括通过至少一个跨越支撑件附接到同心的，升高的内环的外环。 内环包括附接到内圈的内周的手柄。 每个侧面结构包括至少一个突出的连接柄脚和至少一个接收槽口。 附接脚还包括头元件和主体元件。 主体元件从内环轴向延伸并且头元件从主体元件径向延伸。 附接柄脚和接收凹口位于内圈上，使得当两个侧面结构被连接在一起时，一个侧面结构上的连接柄脚与第二侧面结构上的相应的接收凹口相配合并由其接收。
