Embodiment Construction

[0021] figure 1 An exemplary mandrel 10 of the present invention is shown. The mandrel 10 includes a main body 12 and spacer members 14a, 14b and 14c. The spacer members include arms 16a, 16b, and 16c, respectively, and protrusions 18a, 18b, and 18c, respectively. The mandrel of the present invention may include one or more spacer members as desired.

[0022] The body is elongated with a longitudinal axis.

[0023] The spacer members may be arranged at equal positions on the longitudinal axis of the mandrel, ie at substantially equal distances from their common ends, to function concurrently with the same coil. The spacer members may be located at different positions on the longitudinal axis of the mandrel, ie at substantially different distances from their common ends, as desired to function in accordance with the invention where the coils have different widths.

[0024] exist figure 1 In the embodiment shown, the body is generally cylindrical, i.e., elongated, except ...

Abstract

Spindles (10) adapted to receive a tape roll having a core opening thereof and comprising an elongate body (12) and at least one spacing member (14a, 14b, 14c) comprising a protuberance (18a, 18b, 18c) wherein the protuberance is configured such that it can be configured in a first protruding position and in a second non-protruding position. Also, dispensers comprising such spindles, methods of assembling such dispensers, and methods of dispensing tape from tape rolls mounted on such spindle.

Description

technical field [0001] The present invention relates to mandrels and dispensers for roll products. Background technique [0002] Some adhesive-backed and some non-adhesive-backed tape products (e.g., paper for office use, medical use, etc., decorative tape, and adhesive tape) are often in roll form supplied and then dispensed by unwinding from rolls. In many dispenser configurations, a roll comprising in some cases an annular core and in other cases no core is mounted on a mandrel about which the roll is rotated as tape is removed from the roll. In many dispensers, the dispenser is configured to support the mandrel and the roll mounted on the mandrel in the position and orientation required for dispensing, e.g. easy finger access to the end of the strip to allow grasping, easy access Cutting blades to allow easy separation of the desired portion of the strip from the rolled portion, etc. [0003] While some dispenser configurations are configured for a single roll of tape...
