Abstract: A horizontal form-fill-seal packaging machine includes a former for forming a film into a tubular configuration, a conveyor for feeding articles into the tubular film one after another, a fin sealer for sealing lapped edges of the tubular film, an end sealer for sealing the tubular film in a crosswise direction thereof in a position between two adjacent articles, and a film feeding mechanism for feeding the film supplied from a film source into the end sealer via the former and the fin sealer. A plurality of pushers are mounted on the conveyor and equi-distantly spaced from each other in the feeding direction of the articles. Each of the pushers defines the position of a rear end of the article. A length detector sequentially detects the length of the articles in the feeding direction. A controller controls the conveyor and the end sealer in response to the length of each article detected by the length detector.
Abstract: An implantable body including an outer membrane forming an enclosure for receiving a filler material. The surface of the outer membrane is characterized by a random distribution of peaks separated by valleys. The peaks and valleys are separated by gradual contoured slopes with a smooth transition between the peaks and valleys which are substantially free from indentation. The enhanced surface provides improved anchoring of the implant, yet reduces host reaction. The enhanced surface is formed by depositing a distribution of cured polymeric particles on an uncured tacky surface. This intermediate surface is then cured, followed by application of a layer of uncured elastomeric material. The entire surface is then cured to form the enhanced surface.
