摘要:
A portable conveyor belt splicing apparatus is provided that includes an upper press assembly and a lower press assembly which include, respectively, upper and lower platen assemblies. The upper and lower press assemblies may each include a forced air cooling system for rapidly cooling platens of the platen assemblies. The upper and lower press assemblies may include insulating assemblies with resilient members that support the upper and lower press assemblies. The resilient members provide structural support and insulate the platens from the frame which reduces the power required to heat the platens. In one form, the apparatus includes a power supply circuit that can alternate between providing power to upper and lower heaters in response to the apparatus being connected to different types of standard power supplies. Further, the power supply circuit permits the use of a single recipe for a particular belt irrespective of the type of power supply.

The invention relates to a method for providing a tire with an informative label. The method comprises supporting a tire, supplying a banding material to the tire and wrapping it in a loop around a part of the tire, holding the banding material at the neck of said loop, and connecting opposed areas of the banding material at said neck to form a label wrap. The invention further relates to an apparatus for carrying out the method and to a tire provided with the label. The informative label is easily removed by a mechanic and shows an improved processability and printability. The informative label further does not leave any adhesive or other residuals on a tire.

A belt welding apparatus is provided for joining together the ends of one or more monolithic conveyor belts. In one form, a belt support is configured to support the belt ends in spaced relation to each other and a non-contact heating device is provided for being disposed between the belt ends to generate thermal radiation for joining the belt ends together. In one form, the non-contact heating device is a ribbon heating device. In another form, a drive mechanism is operable to cause relative movement of a pair of platens, for supporting belt ends, toward and away from each other and a heating device between heating and stowed positions. An actuator of the drive mechanism is movable by an operator between at least three operation positions corresponding to three different operation positions of the platens.

Annular elastic band for retaining objects of various shape and size, which is constituted by a film of plastic material with ring-like extension and with thickness comprised between 6 µm and 300 µm. Such annular band (1) is composed of at least two elongated tape-like bands (2, 3), each of which provided at its ends with junction flaps (27, 28) which are superimposed on the junction flaps (27, 28) of the other band (2, 3). Fixing means (4) are provided for fixing together the superimposed junction flaps (27, 28) of the two bands (2, 3), each of which comprising at least two external layers (9) composed of a first extrudable plastic material, and an internal layer (10) composed of a second extrudable plastic material, interposed between the two external layers (9) and composed of at least two superimposed internal substrates (10') preferably made of polyethylene and closely joined together via adhesion by means of penetration of polymer chains of each substrate (10') in the other substrate (10') via collapse with hot compression.

The present invention relates to a method for sealing a wristband or providing a closure for a wristband directly around the wrist, wherein the method comprises steps for: placing a band part with a free end around the wrist, the band part forming an end part of a band supply, adjusting a size of the wristband to the wrist, sealing the band part by means of a connecting operation, separating the band part from the band supply, and relates to a wristband sealing device for sealing a wristband or providing a closure for a wristband directly around the wrist, wherein the device comprises: means for supplying a band part, the band part forming an end part of a band supply, means for placing a wrist thereon, means for creating a seal by means of a connecting operation.
摘要:
L'invention concerne un dispositif de jonction (10) pour fermer une bande de matière (1) en boucle, comportant deux éléments de jonction (20, 30) liés intimement aux extrémités (2, 3) de la bande de matière (1), assemblés entre eux par emboitement de deux dentures (22, 32), et verrouillés par une tige de verrouillage (15) transversale insérée dans les orifices transversaux (14) alignés des dents (13) de chaque denture. Les éléments de jonction (20, 30) sont réalisés dans une matière compatible avec celle de ladite bande de matière, et comportent une âme de traction s'étendant longitudinalement jusque dans les dents (13) en entourant l'orifice transversal (14) des dents (13) de chaque denture (22, 32) de sorte que, lorsque le dispositif de jonction (10) est assemblé et verrouillé, les âmes de traction des éléments de jonction garantissent la résistance à la traction dudit dispositif de jonction (10), tout en restant très souple en flexion.
