Title: Method of controlling a turret winder
Inventor: LOCKWOOD FREDERICK EDWARD
IPC: B65H19/12
Filed: 1996-05-22
Abstract: A web winding apparatus (90) and a method of operating the apparatus are disclosed. The apparatus can include a turret assembly (200), a core loading apparatus (1000), and a core stripping apparatus (2000). The turret assembly (200) supports rotatably driven mandrels (300) for engaging hollow cores (302) upon which a paper web (50) is wound. Each mandrel (300) is driven in a closed mandrel path (320), which can be non-circular. The core loading apparatus (1000) conveys cores (302) onto the mandrels (300) during movement of the mandrels (300) along the core loading segment (322) of the closed mandrel path (320), and the core stripping apparatus (2000) removes each web wound core (302, 51) from its respective mandrel (300) during movement of the mandrel (200) along the core stripping segment (326) of the closed mandrel path (320).  The turret assembly (200) can be rotated continuously, and the sheet count per wound log (51) can be changed as the turret assembly (200) is rotating. The apparatus (90) can also include a mandrel (300) having a deformable core engaging member (3100). The web (50) is transferred from a driven bedroll (59) to the turret assembly (200). The turret assembly (200) is individually driven and mechanically decoupled from the bedroll (59). The core loading apparatus (1000) and the core stripping apparatus (2000) are both indiviudally driven and are mechanically decoupled from the rotation of the bedroll (59) and of the turret assembly (200). A common position reference is provided which can be a function of the angular position of the bedroll (59) or a function of its accumulated number of revolutions. The position of the turret assembly (200), the core loading apparatus (100) and of the core stripping apparatus (2000) is controlled in relation to the common position reference.

IPC: G01K7/12
Filed: 1998-01-19
Abstract: A temperature sensing device includes a head piece having a solid metal body with a mounting surface and a recess within the mounting surface for receiving a thermocouple therein. The body has an attachment end, and hole extending through the attachment end which communicates with the recess such that a plurality of leads may extend through the hole and connect to the thermocouple. An insulating material of mica or metal oxide surrounds the leads and the conducting portions of the thermocouple so as to insulate them from each other and from the metal body of the enclosure. Several structures can be used to form the thermocouple fitted into the small enclosure. In one embodiment, a thermocouple is formed using thin strips of conducting material made of alloys suitable for forming a thermocouple. A thermocouple may be made by first removing the sheathing and insulation from the end of a thermocouple cable, exposing the leads and the leads are flattened or other wise shaped. Also the diameter of such cables can be reduced by subjecting them to a drawing process or a swedging process wherein the outer diameter of the sheath of the cable is reduced as is the diameters of the alloy leads within the cable. To maximize the accuracy of the thermocouple, the junction at the end of the cable can be turned 90 degrees and the junction positioned within the enclosure to abut against the surface, the temperature of which is to be measured.
