The present invention discloses a roll holder for tape dispenser and a tape dispenser assembly therewith. The roll holder comprises a cylindrical body and an annular portion made from a material having a high friction coefficient, the annular portion being fixed inside the cylindrical body. The roll holder tape dispenser is supported by a shaft. Two cylindrical bodies are connected to a roll of tape, one at each extremity of the tape spool by press-fitting. The shaft passes through the annular portion and the friction occurring between the shaft and annular portion induce a tension in the tape when the tape is unwound from the roll.

This invention relates to an improvement in an apparatus for dispensing a ribbon between layers of web material and more particularly, to an automated and remote positioning system of ribbon dispensers which are precisely positioned with respect to the web material by a controlling and monitoring system and are physically easily accessible for maintenance by an operator. The automated and remote positioning system of ribbon dispensers includes locking means interacting with either the apparatus or with a traversing mechanism such as a lead screw to move the ribbon dispensers.
摘要:
An apparatus to prevent strip material from falling off the edges of a strip material package when unwinding. The package comprises a generally cylindrical and flangeless core around which the strip material is wound transversely in a plurality of overlapping layers. The apparatus also includes an idler roller. When unwinding, the strip material goes around the idler roller, then around the package, generally in its central portion and then again around the idler roller before being fed to a laminating machine. A method to use the apparatus is also provided.

Peptides exhibiting anti-viral and anti-fusogenic activity are modified to provide greater stability and improved half-life in vivo. The selected peptides include fusion inhibitors DP178 and DP107 and related peptides and analogs thereof. The modified peptides are capable of forming covalent bonds with one or more blood components, preferably a mobile blood component.

This invention relates to glucagon-like peptide 2 (GLP-2) derivatives. In particular this invention relates to GLP-2 peptide derivatives having an extended in vivo half-life, for the treatment or prevention of gastrointestinal disorders or diseases such as inflammatory bowel disease and other gastrointestinal functions, from any segment of the gastrointestinal tract, from the oesophagus to the anus.
