Apparatus suitable for guaranteeing a quick and automatic change of materials wound on reels, said apparatus consisting mainly of a reel-alternating mechanism combined with a mechanism for cutting and reconnecting the reeled material.

A vinyl roll storage and dispensing apparatus that is operable to receive and store a plurality of vinyl rolls wherein at least two of the vinyl rolls are oriented in axial alignment and vertically stacked. The vinyl roll storage and dispensing apparatus further includes a base platform having a first support member and a second support member being planar in manner wherein the second support member is superposed the first support member and rotatably mounted thereto. A central post member is mounted to the second support member and extends upwards therefrom. A plurality of channels are formed within the central post member. At least two vinyl roll engagement members are present and are operable to receive and retain a vinyl rolls therein. The vinyl roll engagement members are configured to stack at least two vinyl rolls in a vertical orientation.

The invention relates to an assembly for contactlessly measuring the thickness of a continuous material web, in particular a flexible, elastic, and/or coated material web, having: a material web which is guided on the surface of a contact body, in particular a contact body which is cylindrical at least in some sections; and a sensor assembly for measuring the thickness of the material web, wherein at least one first sensor is oriented toward an upper face of the material web and at least one second sensor, lying opposite the first sensor, is oriented toward a lower face of the material web. The invention is characterized in that the second sensor is at least partially arranged below the contact region between the material web and the contact body.

A support device includes: two support arms movably supported along an axial direction; a driver causing the support arms to approach and separate; and two chucks rotatably mounted on tip portions of the support arms for supporting a paper roll. The chucks include: a main body having an outer diameter decreasing toward a tip portion, and guide parts along the axial direction provided on an outer circumference; and a support members including a receiving part movably supported by the guide parts and for contacting an end of the paper roll, and a support part for contacting an inner circumference of the paper roll. A movement unit includes a movement member for contacting the support members and moves the support members to the tip portion side by the movement member. A force applying device applies force in such a direction that the support members and the movement member approach each other.
